This presentation discusses what linkage is, the kinds of linkage, and linkage groups. It also discusses pedigree analysis for the inheritance of genetic disorders in a family.
Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.

Definition of Linkage, Coupling and Repulsion hypothesis, Linkage group- Drosophila, maize and man, Types of linkage-complete linkage and incomplete linkage, Factors affecting linkage- distance between genes, age, temperature, radiation, sex, chemicals and nutrition, Significance of linkage.
The tendency of two or more genes to stay together (i.e., the co-existence of two or more genes) in the same chromosome during inheritance is known as LINKAGE. The linked genes are present on the same chromosome are said to be SYNTENIC. The linked genes do not show independent assortment.
LINKAGE v/s INDEPENDENT ASSORTMENT
The frequency of linkage or the strength recombination is influenced by several factors (agents).

A Strategic Approach: GenAI in EducationPeter Windle
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.

Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
it describes the bony anatomy including the femoral head , acetabulum, labrum . also discusses the capsule , ligaments . muscle that act on the hip joint and the range of motion are outlined. factors affecting hip joint stability and weight transmission through the joint are summarized.

Genetics Lesson

Ms. Lichtenwald
Genetics
2. Goals
By the end of this lesson, you should meet the following
Michigan Merit Curriculum course requirements for Genetics
and Inherited Traits:
B4.1A Draw and label a homologous chromosome pair with heterozygous alleles
highlighting a particular gene location.
B4.1B Explain that the information passed from parents to offspring is
transmitted by means of genes that are coded in DNA molecules.
B4.1C Differentiate between
dominant, recessive, codominant, polygenic, and sex-linked traits.
B4.1E Determine the genotype and phenotype of monohybrid
crosses using a Punnett Square.
3. Definitions
Chromosome: A chromosome is an organized package of DNA found in the
nucleus of the cell.
Gene: The gene is the basic physical unit of inheritance, is passed from parents to
offspring and contains the information needed to specify traits. Genes are
arranged, one after another, on structures called chromosomes.
Allele: An allele is one of two or more versions of a gene. An individual inherits
two alleles for each gene, one from each parent.
Dominant: If the alleles of a gene are different, one allele will be expressed; it is
the dominant gene.
Recessive: If the alleles are different, the dominant allele will be expressed, while
the effect of the other allele, called recessive, is masked.
Genotype: The two alleles inherited for a particular gene. The expression of the
genotype contributes to the individual's observable traits, called the phenotype.
Phenotype: A phenotype is an individual's observable traits, such as height, eye
color, and blood type.
Homozygous: Homozygous is a genetic condition where an individual inherits
the same alleles for a particular gene from both parents.
Heterozygous: A phenotype is an individual's observable traits, such as
height, eye color, and blood type.
Trait: A trait is a specific characteristic of an organism.
4. Dominance
A dominant trait is represented by a capital letter
while a recessive trait is represented by the
lowercase of the same letter as the dominant.
Each parent passes on one allele of each trait to
their offspring.
The two alleles inherited is the genotype of a
specific trait.
5. In a pea plant, the dominant allele
for height may be represented by a
capital T, for tall.
Click on the letter that represents the
recessive allele for short height?
6. Genotypes
Heterozygous: Homozygous:
Click on each letter to see the difference
between heterozygous and homozygous
genotypes.
B B Bbbb
7. Phenotypes
The phenotype is the physical trait coded by the alleles in the genotype.
Spherical pea plant seeds are
dominant over dented.
Click on the alleles that
make up the genotype for a
homozygous dominant pea
plant for this trait.
8. The Monohybrid Cross
A Punnett square crosses the genotype of a specific trait from each parent
to show what the offspring might inherit from the parents.
The cross below shows a mother with curly hair and a father with
straight hair. Curly hair is the dominant trait.
Cc X cc
C c
Genotypic ratio:
2-Cc, 2-cc 1:1 c Cc cc
Phenotypic ratio:
2-dominant, 2-recessive
1curly:1straight = 1:1
c Cc cc
10. The Monohybrid Cross
A heterozygous female was crossed with a heterozygous male for the trait
for ear lobe attachment. Attached ear lobes is the recessive trait.
Cc X Cc
Click on the correct
phenotypic ratio of attached
to free ear lobes for this
monohybrid cross.
0:4 = 0 attached to 4 free Set up the
1:3 = 1 attached to 3 free cross to
2:2 (or 1:1) = 2 attached to 2 free determine
3:1 = 3 attached to 1 free the
4:0 = 4 attached to 0 free phenotypic
ratio.
11. Punnett Square Practice
Click here to be directed to a
website do practice a few more
monohybrid crosses.
When you are done with the monohybrid cross practice
problems, return here to view terms for the next lesson.
12. Terms for next time!
Codominance: Codominance is a relationship between two versions of
a gene. In codominance, neither allele is recessive and the phenotypes of
both alleles are expressed.
Polygenic: A polygenic trait is one whose phenotype is influenced by
more than one gene.
Sex-linked traits: Sex linked is a trait in which a gene is located on a sex
chromosome. In humans, the term generally refers to traits that are
influenced by genes on the X chromosome.
