This document discusses several types of gene action and inheritance patterns, including complete dominance, incomplete dominance, codominance, overdominance, gene interactions, epistasis, pleiotropy, sex-linked genes, penetrance, and essential genes. It provides examples for each type, such as ABO blood groups showing codominance and coat color in mice demonstrating epistasis.
Biology Form 5 Chapter 5 : 5.1 Inheritance
- Gregor Mendel conducted experiments with pea plants in the 1860s and is considered the founder of genetics. Through his experiments, he discovered the fundamental laws of inheritance.
- Mendel determined that traits are passed from parents to offspring through "factors" that we now know as genes. His laws of inheritance include dominance, segregation, and independent assortment.
- Mendel's work formed the basis for understanding how traits are inherited and laid the foundation for modern genetics.
Genetics non mendelian
This document discusses several patterns of inheritance beyond simple dominant and recessive traits. It describes incomplete dominance, where the heterozygous phenotype is intermediate between the two homozygous phenotypes. Codominance is defined as when both alleles are fully expressed in the heterozygote without blending. Multiple alleles exist for some traits, where more than two alleles determine the phenotype. Sex linkage is explained, where traits are inherited through genes on the X or Y chromosomes. Polygenic traits are influenced by multiple gene pairs and are usually continuous traits like height or skin color that are also affected by environment.
Incomplete and co dominance ppt
The document discusses two genetic concepts: incomplete dominance and codominance. In incomplete dominance, the heterozygous genotype produces an intermediate phenotype between the two homozygous genotypes. For example, in flowers red and white petal color show incomplete dominance, where heterozygotes are pink. Codominance occurs when both alleles are fully expressed in the heterozygote. For example, in cattle black and white coat colors are codominant, where heterozygotes are spotted. The document provides examples calculating genotypic and phenotypic ratios for offspring from crosses involving these inheritance patterns.

GENE INTERACTIONS SMG
Gene interactions play an important role in inheritance and can produce phenotypes that do not follow typical Mendelian ratios. There are two main types of gene interactions - allelic and non-allelic. Allelic interactions occur between alleles of the same gene and can be complete dominance, incomplete dominance, or co-dominance. Non-allelic interactions occur between genes and can be simple interactions like those controlling comb patterns in chickens, or more complex interactions like epistasis where one gene suppresses the expression of another. Understanding gene interactions is crucial for explaining exceptions to Mendelian inheritance.
MIC150 - Chap 2 Extension Of Mendelian Genetics
This document discusses extensions of Mendelian genetics beyond simple dominant-recessive inheritance. It introduces concepts like codominance, incomplete dominance, multiple alleles, lethal alleles, and linked genes. Codominance occurs when both alleles for a gene are fully expressed in the heterozygote. In incomplete dominance, the heterozygote exhibits an intermediate phenotype between the homozygotes. Multiple alleles exist at a single gene locus with more than two allelic forms. Lethal alleles cause death if homozygous. Linked genes tend to be inherited together due to their proximity on the same chromosome.
Genetics chapter 4 part 2(1)
Gene interactions can modify Mendelian ratios expected from monohybrid and dihybrid crosses. There are several types of gene interactions:
1. Complementary gene interaction results in a 9:7 ratio when two genes work together to produce a trait.
2. Duplicate gene action occurs when genes encode redundant functions, resulting in a 15:1 ratio.
3. Dominant gene interaction yields a 9:6:1 ratio when dominance of one gene masks the other.
4. Epistatic interactions alter Mendelian ratios by one gene modifying another's expression. This includes recessive epistasis (9:3:4 ratio) and dominant epistasis (12:3:1 ratio).
Extension to Mendel's Law - 2015/02/20
This document discusses several concepts related to genetics:
1. It describes incomplete dominance and codominance, using the example of flower color in petunias.
2. It explains lethal alleles and how they can cause death in homozygous or heterozygous individuals. Examples given include coat color in mice and genes in cattle and humans.
3. Multiple alleles are discussed, which have varying levels of dominance and control traits like eye color in fruit flies and coat color in rabbits.
Genetics : Principles of Inheritance and Variation
This document provides information on principles of inheritance and variation, including:
- Key terms like allele, phenotype, genotype, and types of crosses like monohybrid and dihybrid.
- Mendel's experiments with pea plants and his laws of inheritance including dominance, segregation and independent assortment.
- Other inheritance patterns like incomplete dominance, multiple allelism, co-dominance, and sex determination systems.
- The chromosomal basis of inheritance proposed by Sutton and Boveri, including linkage, recombination and Morgan's experiments in Drosophila.
- Examples of Mendelian disorders like hemophilia and sickle cell anemia.
INCOMPLETE DOMINANCE VS CO-DOMINANCE
Incomplete dominance results in a blending of the dominant and recessive alleles such that the phenotype is intermediate between the two pure phenotypes. Codominance results in both alleles being fully expressed together in the heterozygote such that the phenotype shows a combination of both. Examples include snapdragons that are pink when heterozygous for red and white alleles under incomplete dominance, and human blood types that are type AB when heterozygous for the A and B alleles under codominance.
Genetics Notes
1. The document explains genetic crosses and Mendelian inheritance through examples of monohybrid and dihybrid crosses in pea plants.
2. It discusses key genetics concepts like genotype, phenotype, probability, Punnett squares, and inheritance patterns like complete dominance, incomplete dominance, and codominance.
3. As an example, a monohybrid cross between a homozygous dominant purple pea plant and a homozygous recessive white pea plant would result in all heterozygous purple offspring.
AP Bio Ch 12 Power Point
- Gregor Mendel, an Augustinian monk in the late 1800s, is considered the founder of genetics for his experiments breeding pea plants. He studied traits like flower color, seed texture, and pod shape.
- Mendel discovered that traits are passed from parents to offspring through discrete units called genes, located on chromosomes. Genes come in different forms called alleles that give rise to different traits.
- Through experiments breeding thousands of pea plants, Mendel determined that alleles segregate and assort independently during reproduction according to his laws of inheritance. This laid the foundation for modern genetics.
Nonmendelian genetics
- Gregor Mendel conducted experiments with pea plants in the mid-1800s to study inheritance patterns of traits. Through his work with true-breeding pea strains, he discovered that traits are inherited as discrete units (now called genes) that can be dominant or recessive.
- In monohybrid crosses studying one trait, Mendel observed dominant traits appearing in the F1 generation and a 3:1 ratio of dominant to recessive traits in the F2 generation. This supported his theory that traits are inherited through discrete units (genes/alleles) that segregate and assort independently during reproduction.
- Mendel's work formed the basis of classical/Mendelian genetics and helped explain patterns
Dihybrid cross
This Power Point Presentation is designed to explain Mendel's experiment on hybridization and dihybrid cross which considers inheritance of two traits at a time and to know whether they are inherited independently or are influenced by each other and also about Law of Independent assortment
Codominance
Examples of Codominance. The best example, in this case, is the codominance blood type. ABO group is considered to be a codominant blood group where both father’s and mother’s blood group is expressed. It means that the properties of the blood groups exist in the ABO type.
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
Modification of Normal Mendelian ratios with Lethal gene effcets and Epistasis
This document discusses Mendelian genetics and how ratios from monohybrid and dihybrid crosses can be modified. It explains different types of gene interactions including incomplete dominance, codominance, lethal genes, and epistasis. Epistasis refers to interaction between alleles at different loci that modifies phenotypic ratios. Several examples are given to illustrate different types of epistatic interactions like recessive epistasis, dominant epistasis, and duplicate gene interactions. The document also provides tables comparing standard Mendelian ratios to ratios resulting from these various genetic modifications.
Inheritance
Gregor Mendel conducted experiments with pea plants to study inheritance of traits. He found that traits are inherited based on discrete units called genes. Genes exist in pairs and can be dominant or recessive. Through his experiments with monohybrid and dihybrid crosses, Mendel discovered his two laws of inheritance - the Law of Segregation and the Law of Independent Assortment. These laws form the basis of modern genetics.
Mendelian Laws of Inheritance
This document discusses Gregor Mendel's laws of inheritance based on his experiments breeding pea plants. It defines key genetic terms and describes Mendel's three laws: 1) The Law of Dominance states that one allele is dominant over the recessive allele. 2) The Law of Segregation states that alleles segregate and pass to offspring independently during gamete formation. 3) The Law of Independent Assortment states that different genes assort independently of one another during gamete formation. Mendel's laws established basic principles of heredity and laid the foundation for genetics.
Gene interaction ns-w12

Mendellian Inheritance and Gene Action
The document summarizes Gregor Mendel's experiments with pea plants that laid the foundation for the modern understanding of genetics and heredity. It discusses Mendel's observations of inherited traits in pea plants and how this led him to discover the three laws of inheritance: 1) the law of dominance, 2) the law of segregation, and 3) the law of independent assortment. It also explains some of Mendel's experimental methods and variables he controlled that contributed to his success, such as choosing simple and contrasting traits to study. Finally, it provides examples of genetic crosses and inheritance patterns including monohybrid and dihybrid crosses using Punnett squares.
Mendelian genetics
Gregor Mendel conducted experiments with pea plants to study inheritance and genetics. He found that traits are passed from parents to offspring through discrete units (now known as genes). Mendel identified two laws of inheritance: the Law of Dominance and the Law of Segregation. The Law of Dominance states that some traits (called dominant traits) are expressed even if only one gene is present, while other traits (called recessive traits) are only expressed if two copies of the gene are present. The Law of Segregation states that organisms pass only one of their two genes for each trait randomly to their offspring. Mendel's experiments were the foundation of classical genetics and laid the basis for understanding inheritance.
Incomplete dominance
Incomplete dominance is a type of inheritance where neither allele for a trait is dominant. When hybridizing two purebred parents with different alleles, the offspring express a combined intermediate phenotype rather than one or the other parental phenotype. For example, when crossing a red flower with a white flower, the hybrid offspring are pink instead of red or white. A cross between red and blue flowers produces purple offspring rather than red or blue.
Mendel's Law and Inheritance
This document discusses genetic inheritance and provides examples using flower petal color. It defines key genetic terms like gene, allele, genotype and phenotype. It explains homozygous and heterozygous crosses, showing offspring have the dominant trait in the F1 generation and a 3:1 ratio in the F2 generation. A test cross can determine if an organism is homozygous or heterozygous dominant. Co-dominance is when two alleles are equally expressed, like red and white flowers producing pink offspring.

Section10
DNA controls the production of proteins in cells and contains the genetic instructions passed down from parents. It is made up of nucleotides that form the shape of a twisted ladder. In 1953, Watson and Crick determined that DNA has a double helix structure. Three types of RNA - mRNA, tRNA, and rRNA - help in the process of protein synthesis by transcribing DNA and transporting amino acids. The sequence of nucleotides in DNA is read in groups of three to determine which amino acid each codon codes for.
Section7
Cellular energy is stored in ATP, which is made of adenine, ribose, and three phosphate groups. ATP breaks down into ADP and phosphate, releasing energy. Cellular respiration uses oxygen to break down glucose into carbon dioxide, water, and ATP through three stages: glycolysis, the Krebs cycle in mitochondria, and the electron transport chain on mitochondrial membranes. Without oxygen, some cells perform anaerobic respiration through lactic acid fermentation in muscles or alcoholic fermentation in yeast. Photosynthesis uses sunlight, carbon dioxide, and water to produce glucose and oxygen through light-dependent and light-independent reactions.
Section14
1) Charles Darwin developed the theory of evolution by natural selection after observing evidence during his voyage on the HMS Beagle and being influenced by Thomas Malthus' ideas about population growth.
2) Darwin proposed that species evolve over generations through natural selection of heritable traits that aid survival and reproduction in their environments.
3) Other influential early evolutionists included Jean-Baptiste Lamarck who proposed the inheritance of acquired traits, Charles Lyell who demonstrated the power of geologic forces over long periods, and James Hutton who viewed the Earth as shaped by gradual processes over deep time.
Bringing Reading and Writing into the Biology Classroom
The presenters argue that integrating English II concepts into the biology classroom benefits both subjects by reinforcing common academic language and increasing students' vocabulary and writing skills. They provide examples of using quotes to prompt essays explaining scientific concepts and position papers analyzing biology-related decisions to address objectives in both the science and English frameworks. The presenters encourage collaboration between English and science teachers to jointly develop assignments that teach cross-curricular content and skills.
Section15
An ecosystem is composed of communities of organisms and their physical environments. Producers (autotrophs) can produce their own food, while consumers (heterotrophs) obtain energy by eating producers or other consumers. Primary consumers eat producers, secondary consumers eat primary consumers, and decomposers break down dead organisms into detritus. A food chain represents a single pathway of energy transfer starting with a producer, while a food web depicts overlapping food chains within an ecosystem.

06_Notes_Non-Mendelian_Genetics_Student.ppt
This document discusses several types of non-Mendelian inheritance patterns:
1. Incomplete dominance results in a third phenotype between the two parental traits. A red/white flower cross results in pink flowers.
2. Codominance occurs when both alleles are fully expressed in the phenotype, such as black and white fur in a spotted cow.
3. Multiple alleles exist for a single trait, like multiple coat color genes in animals.
4. Polygenic traits are influenced by multiple genes, such as human skin color.
5. Sex-linked traits are carried on the X or Y chromosome, so males usually exhibit the trait since they only have one X chromosome. Color blindness is given as an example

Heredity: inheritance and variation LESSON IN SCIENCE 9
This document discusses several types of non-Mendelian genetics inheritance patterns:
1) Incomplete dominance results in a blended phenotype between two traits when hybrids are formed rather than one trait dominating. An example is red and white flowers producing pink hybrids.
2) Codominance occurs when both alleles are fully expressed together in the hybrid phenotype. For example, a black and white cow producing a spotted hybrid.
3) Multiple alleles exist for a single trait, such as multiple coat color alleles in many animals.
4) Polygenic traits are influenced by multiple genes interacting together, like human skin tone.
5) Sex-linked traits involve genes on the sex chromosomes. Examples include color blindness,
Lesson 14.1
A karyotype shows the complete set of chromosomes arranged in pairs by size. Studying karyotypes is important for understanding human genetics. Humans have 46 chromosomes, including two sex chromosomes that determine sex (XY for males and XX for females). The other 44 chromosomes are called autosomes. Many human traits are inherited according to patterns of simple dominance, codominance, or sex-linked inheritance. Pedigree analysis can be used to determine the inheritance patterns of traits within families.
Genetics and heredity

2014 sex-linkage
Sex linkage refers to the phenotypic expression of an allele that is related to the chromosomal sex of an individual. Sex determination is the biological system that determines the development of sexual characteristics in an organism. Examples of sex determination mechanisms include genotypic sex determination, where sex is governed by genotype, and genic sex determination, which does not involve sex chromosomes.
Basics of Genetics presented by waseem javid
This document provides an overview of genetics concepts including:
- Gregor Mendel is considered the "Father of Genetics" and discovered the principles of inheritance including independent assortment.
- Traits are determined by genes located on chromosomes, which are received in homologous pairs from each parent. Genes can be dominant, recessive, or codominant.
- A Punnett square can be used to predict the possible genotypes and phenotypes of offspring from a genetic cross based on the parents' genotypes.
- Sex is determined by sex chromosomes, with females typically having XX and males having XY. Sex-linked traits are located on the X chromosome.
- Pedigrees can represent the inheritance of traits through generations
2014-sex-linkage.ppt
This document discusses sex linkage, sex determination, and sex chromosomes. It begins by defining sex linkage as the phenotypic expression of an allele related to an individual's chromosomal sex. Sex determination is defined as the biological system that determines the development of sexual characteristics in an organism. It then discusses several key topics:
- Eukaryotic chromosomes, including that most species are diploid and have homologous chromosome pairs.
- Sex chromosomes, which are the X and Y chromosomes. Females typically have two X chromosomes and males have one X and one Y chromosome.
- Evidence that supported the chromosome theory of inheritance, including Morgan's experiments with white-eyed Drosophila that demonstrated X-linked inheritance.
4.3 theoretical genetics
This document discusses genetics concepts including:
- Genotypes describe an organism's alleles while phenotypes describe its observable characteristics.
- Dominant alleles will be expressed whether homozygous or heterozygous, while recessive alleles only express when homozygous.
- Codominance occurs when both alleles in a heterozygote affect the phenotype.
- Probability crosses can determine the likelihood of offspring inheriting particular traits based on parental genotypes.

The document outlines various facts about chemistry and biology. It discusses that all living things must adapt, get energy, reproduce and be made of cells. It also explains that atoms are made up of protons, neutrons and electrons and that protons and neutrons are in the nucleus while electrons orbit. Additionally, it notes the three types of bonds - hydrogen, ionic and covalent - and provides facts about water chemistry including its chemical formula and polarity.
Section 2 - Scientific Method
The document provides information on scientific equipment, measurement units, the scientific method, experimental design, and graphing. It defines common lab tools like graduated cylinders, pipettes, and microscopes. It explains units of measurement for mass, length, and temperature. It describes the key parts of the scientific method and experimental design, including the importance of controls, placebos, independent and dependent variables. It also gives brief descriptions of line graphs, bar graphs and pie charts.
Section 8 - Cell Reproduction
The document summarizes key facts about cellular reproduction and the cell cycle. It explains that the cell cycle consists of interphase (G1, S, G2 phases) and mitosis (M phase including prophase, metaphase, anaphase and telophase). During interphase, the cell grows and DNA is replicated. Mitosis divides the cell into two identical daughter cells. Meiosis produces gametes through two cell divisions and reduces chromosome number by half to produce haploid cells. Fertilization fuses gametes to form a diploid zygote and restart the cell cycle.
Section 9 - Genetics
Gregor Mendel was an Austrian monk who conducted early experiments with pea plants that formed the basis of genetics. Through his experiments, he discovered that traits are passed from parents to offspring through discrete units (now known as genes) and that some traits are dominant over others. He developed the laws of segregation and independent assortment to describe inheritance patterns. Mendel's work established genetics as a science and he is considered the father of genetics.
Section 7 - Cell Energy
Cellular energy is stored in ATP, which is composed of adenine, ribose, and three phosphate groups. ATP breaks down into ADP and a phosphate group, releasing energy. Cellular respiration uses oxygen to break down glucose into carbon dioxide, water, and ATP through three stages: glycolysis, the Krebs cycle in mitochondria, and the electron transport chain on mitochondrial membranes. Without oxygen, some cells perform anaerobic respiration through lactic acid fermentation or alcoholic fermentation. Photosynthesis uses sunlight, carbon dioxide, and water to produce glucose and oxygen through light-dependent and light-independent reactions. Photosynthesis and cellular respiration are essentially reverse processes.
Section 4 - Biochemistry
This document provides 40 factoids about organic chemistry and biochemistry. It defines organic chemistry as the study of carbon compounds produced by living things.

Section6
The cell membrane is selectively permeable, allowing some substances to enter and leave the cell. The phospholipid molecules that make up the cell membrane have hydrophilic heads and hydrophobic tails. There are two types of cellular transport: passive transport, which moves substances down a concentration gradient without energy, and active transport, which moves substances against a concentration gradient and requires energy. The three types of passive transport are simple diffusion, facilitated diffusion, and osmosis, while active transport includes exocytosis, endocytosis, and various pumps.
Section11
This document provides 200 facts about taxonomy and the classification of organisms. It discusses the 7 levels of biological classification from kingdom to species. Scientific names use binomial nomenclature, consisting of the genus and species names. Viruses are not considered living organisms and are not classified within the traditional biological taxonomy. The four main kingdoms are Archaebacteria, Eubacteria, Protista, and Fungi. Each kingdom has distinguishing characteristics.
Chapter 2 Lecture Notes
1) Water is a versatile solvent that is fundamental to life processes due to its polarity and ability to form hydrogen bonds. Hydrogen bonding gives water unique properties like being less dense as a solid and having a high heat capacity.
2) The chemistry of life is sensitive to acidic and basic conditions. Acids increase the concentration of hydrogen ions while bases decrease it. The pH scale measures whether a solution is acidic, basic, or neutral.
3) Chemicals in living things are arranged in a hierarchy from atoms to molecules to macromolecules and cells. Life requires 25 essential elements that form the compounds which make up organisms through ionic and covalent bonds.
Ecosystems
The document discusses key concepts in ecology including ecosystems, energy flow through ecosystems, and different biomes. It describes producers that capture energy from the sun or chemosynthesis, consumers that eat producers or other consumers, and decomposers that break down dead organisms. Food chains and food webs show the transfer of energy between organisms. Biomes are characterized by their climate and include terrestrial biomes like tundra, forests, grasslands, and deserts as well as aquatic biomes like freshwater and saltwater habitats.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
