Genetics-and-Heredity-Intro-
Genetics is the science of heredity, or how traits are passed from parents to offspring. Traits are determined by genes located on chromosomes. Gregor Mendel's experiments with pea plants in the 1800s laid the foundations for genetics by demonstrating that traits are inherited in predictable patterns depending on whether genes are dominant or recessive. The basic principles of inheritance that Mendel discovered include that each parent contributes half of the offspring's genes, and that dominant traits mask recessive traits. Genetic inheritance can be represented using Punnett squares to predict offspring genotypes and phenotypes.
Genetics
This document provides information about genetics and Mendelian inheritance. It begins with an introduction to important figures in the history of genetics like Gregor Mendel. It then discusses the three main theories of inheritance pre-Mendel and the history of genetics including Mendel's experiments and laws of inheritance. The rest of the document details various genetics concepts like linkage, crossing over, aneuploidy and their relationships to chromosomes and inheritance patterns.

Mendelian Genetics.pptx
This document discusses Gregor Mendel and the principles of inheritance through Mendelian genetics. It covers key terms like genotype, phenotype, alleles, dominant/recessive genes, and Mendel's laws of inheritance including segregation, independent assortment, and complete dominance. It provides examples of inheritance patterns in traits like eye color, hair color, plant height and flower color. It also presents genetics problems involving setting up punnett squares and determining genotype and phenotype ratios in offspring.
Presentation 02 genetics i
The document discusses several of Gregor Mendel's discoveries and laws of genetics from his experiments with pea plants including:
1) Mendel's law of segregation which states that alleles for a gene separate into gametes during reproduction.
2) His law of independent assortment which states that different genes assort independently if located on separate chromosomes.
3) That dominant alleles are fully expressed in heterozygotes while recessive alleles have no visible effect.
GeneticsProblems.ppsx
This document contains 8 genetics practice problems involving concepts like dominance, recessiveness, sex-linked traits, blood types, and dihybrid crosses. The problems cover monohybrid and dihybrid crosses in plants and humans, determining probabilities of traits being passed on, using blood type information to deduce parent-child relationships, and identifying possible genotypes and phenotypes of offspring.
Powerpoint heredity
The document discusses basic concepts of heredity and genetics, including chromosomes, genes, alleles, dominance, and patterns of inheritance. It explains Mendel's experiments with pea plants and how they led to the concepts of dominant and recessive alleles. It also discusses sex determination, genetic disorders, and using Punnett squares and family trees to predict inheritance patterns.
Genetics, mendelian laws
Mendel's Law of Independent Assortment states that allele pairs separate independently during gamete formation, meaning traits are transmitted independently of one another. Mendel demonstrated this through dihybrid crosses in pea plants, which resulted in a 9:3:3:1 ratio of traits in the offspring. His work established that inheritance follows simple probabilistic rules and discrete factors (genes) are passed from parents to offspring according to the laws of chance.
4.3 theoretical genetics
The document defines key genetics terminology such as genotype, phenotype, dominant and recessive alleles, locus, homozygous, heterozygous, carrier, and test cross. It explains that some genes have multiple alleles and describes ABO blood groups as an example of codominance and multiple alleles. It also explains sex determination in humans using X and Y chromosomes and defines sex linkage, providing examples of color blindness and hemophilia. The document notes techniques for predicting offspring ratios using monohybrid crosses and deducing genotypes from pedigree charts.

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.
Mc chapter 14
1. A baby boy gets his sex chromosomes from different parents - an X chromosome from his mother and a Y chromosome from his father.
2. Two animals with genotypes Aa were mated. Their offspring would probably have a 3:1 ratio of black-haired to white-haired offspring.
3. During mitosis, chromosomes separate so that each new nucleus gets half the normal number of chromosomes.
CROSS (PERSILANGAN).pptx
Genes are segments of DNA that control hereditary traits in organisms. Genes contain genetic information and can be dominant, recessive, or semi-dominant. Alleles are gene variants that appear at corresponding locations on homologous chromosomes. A monohybrid cross involves breeding organisms with homozygous dominant and recessive genotypes for a trait to determine the dominant allele and inheritance patterns. It can also involve breeding heterozygous individuals to confirm allele dominance.
Incomplete, codominance, multiple alleles
1. Incomplete dominance and codominance are genetic concepts where the phenotype of the offspring is not fully dominated by one allele. An example is pink flowers from white and red parent flowers.
2. Codominance is when the offspring shows traits of both parents, like a checkered chicken from a black and white parent.
3. Multiple alleles exist when more than two alleles control a trait, such as blood types A, B, AB, and O in humans which are determined by proteins on red blood cells.
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

1. In a human genetic study, a family with five phenotypically normal children was investigated.
Two children were "homozygous" for a Robertsonian translocation between chromosomes 19
and 20 (they contained two identical copies of the fused chromosome). They have only 44
chromosomes but a complete genetic complement. Three of the children were "heterozygous" for
the translocation and contained 45 chromosomes, with one translocated chromosome plus a
normal copy of both chromosomes 19 and 20. Two other pregnancies resulted in stillbirths. It
was later discovered that the parents were first cousins. Based on this information, determine the
chromosome compositions of the parents. What led to the stillbirths? Why was the discovery that
the parents were first cousins a key piece of information in understanding the genetics of this

Mendelian Genetics.pptx
This document discusses Gregor Mendel and the principles of inheritance through Mendelian genetics. It covers key terms like genotype, phenotype, alleles, dominant/recessive genes, and Mendel's laws of inheritance including segregation, independent assortment, and complete dominance. It provides examples of inheritance patterns in traits like eye color, hair color, plant height and flower color. It also presents genetics problems involving setting up punnett squares and determining genotype and phenotype ratios in offspring.
Presentation 02 genetics i
The document discusses several of Gregor Mendel's discoveries and laws of genetics from his experiments with pea plants including:
1) Mendel's law of segregation which states that alleles for a gene separate into gametes during reproduction.
2) His law of independent assortment which states that different genes assort independently if located on separate chromosomes.
3) That dominant alleles are fully expressed in heterozygotes while recessive alleles have no visible effect.
GeneticsProblems.ppsx
This document contains 8 genetics practice problems involving concepts like dominance, recessiveness, sex-linked traits, blood types, and dihybrid crosses. The problems cover monohybrid and dihybrid crosses in plants and humans, determining probabilities of traits being passed on, using blood type information to deduce parent-child relationships, and identifying possible genotypes and phenotypes of offspring.
Powerpoint heredity
The document discusses basic concepts of heredity and genetics, including chromosomes, genes, alleles, dominance, and patterns of inheritance. It explains Mendel's experiments with pea plants and how they led to the concepts of dominant and recessive alleles. It also discusses sex determination, genetic disorders, and using Punnett squares and family trees to predict inheritance patterns.
Genetics, mendelian laws
Mendel's Law of Independent Assortment states that allele pairs separate independently during gamete formation, meaning traits are transmitted independently of one another. Mendel demonstrated this through dihybrid crosses in pea plants, which resulted in a 9:3:3:1 ratio of traits in the offspring. His work established that inheritance follows simple probabilistic rules and discrete factors (genes) are passed from parents to offspring according to the laws of chance.
4.3 theoretical genetics
The document defines key genetics terminology such as genotype, phenotype, dominant and recessive alleles, locus, homozygous, heterozygous, carrier, and test cross. It explains that some genes have multiple alleles and describes ABO blood groups as an example of codominance and multiple alleles. It also explains sex determination in humans using X and Y chromosomes and defines sex linkage, providing examples of color blindness and hemophilia. The document notes techniques for predicting offspring ratios using monohybrid crosses and deducing genotypes from pedigree charts.

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.
Mc chapter 14
1. A baby boy gets his sex chromosomes from different parents - an X chromosome from his mother and a Y chromosome from his father.
2. Two animals with genotypes Aa were mated. Their offspring would probably have a 3:1 ratio of black-haired to white-haired offspring.
3. During mitosis, chromosomes separate so that each new nucleus gets half the normal number of chromosomes.
CROSS (PERSILANGAN).pptx
Genes are segments of DNA that control hereditary traits in organisms. Genes contain genetic information and can be dominant, recessive, or semi-dominant. Alleles are gene variants that appear at corresponding locations on homologous chromosomes. A monohybrid cross involves breeding organisms with homozygous dominant and recessive genotypes for a trait to determine the dominant allele and inheritance patterns. It can also involve breeding heterozygous individuals to confirm allele dominance.
Incomplete, codominance, multiple alleles
1. Incomplete dominance and codominance are genetic concepts where the phenotype of the offspring is not fully dominated by one allele. An example is pink flowers from white and red parent flowers.
2. Codominance is when the offspring shows traits of both parents, like a checkered chicken from a black and white parent.
3. Multiple alleles exist when more than two alleles control a trait, such as blood types A, B, AB, and O in humans which are determined by proteins on red blood cells.
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

1. In a human genetic study, a family with five phenotypically normal children was investigated.
Two children were "homozygous" for a Robertsonian translocation between chromosomes 19
and 20 (they contained two identical copies of the fused chromosome). They have only 44
chromosomes but a complete genetic complement. Three of the children were "heterozygous" for
the translocation and contained 45 chromosomes, with one translocated chromosome plus a
normal copy of both chromosomes 19 and 20. Two other pregnancies resulted in stillbirths. It
was later discovered that the parents were first cousins. Based on this information, determine the
chromosome compositions of the parents. What led to the stillbirths? Why was the discovery that
the parents were first cousins a key piece of information in understanding the genetics of this
family?.

https://app.box.com/s/y977uz6bpd3af4qsebv7r9b7s21935vdA 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.

- 1. 1. In a given plant, the yellow seed color allele (Y) is dominant to green seed color (y). Give the genotypic and phenotypic ratios for the following crosses? a. homozygous yellow x green b. heterozygous yellow x green c. heterozygous yellow x heterozygous yellow d. green x green 2. If two animals heterozygous for a single pair of genes are mated and have 276 offspring, how many would be expected to have the dominant genotype? 3. Two long-winged fies are mated. The offspring included 90 with long wings and 32 with short wings. Which phenotype is recessive? 4. A blood test reveals that a couple both have the sickle-cell trat. What is the probability of their producing a child with sickle-cell anemia? 5. A blood type A woman has a type B child. She accuses a type O man of being the father. Knowing genetics you are asked to give an opinion; do so. 6. Assume that human eye color is controlled by a single pair of alleles. A blue-eyed man, both of whose parents were bom brown-eyed, marries a brown-eyed woman whose father was blue-eyed and whose mother was brown-eyed. They have a blue-eyed child. Which are the genotypes of all individuals mentioned? 7. A red fruit, tall tomato plant RrTt, is crossed with a yellow-fruited dwarf plant ritt. What genotypes and phenotypes would be expected in the offispring? 8. What genotype and phenotype would be expected in the offspring if the cross in the previous problem had been RrTt x RrTt ?
