Answer #1

If the gene A masks the effect of gene B, then the gene A is called a dominant gene.

Dominant epistasis : when one gene(dominant allele) masks the effects of either allele of the second gene (recessive allele) and the dominant epistasis was mainly caused by masking the action of the recessive gene.

Ratio is 12:3:1 instaed f 9:3:3:1

Example: Summer Squash

Imagine that the head shape is controlled by a maternal effect gene. The dominant h+ allele produces an oval-shaped head, while the recessive h allele produces a square head. Imagine that a woman has a square head. Her father has the h+ h+ genotype. What proportion of head phenotypes do you expect to see in her children? Please provide explanation.

A goldfish is homozygous dominant for O for the gene for orange pigmented scales, but it is also homozygous for the dominant B allele of a gene that causes black scales. Any goldfish with a dominant B allele has black scales. A second goldfish is homozygous for teh recessive o allele of the orange gene and makes no orange, but it is homozygous bb at the black scale gene. This fish is white. A.

6. In humans, a type of blindness called aniridia (B) is dominant over the normal sighted individual (b). Migraine headache (M) is the result of a different dominant gene. A non-migraining man with aniridia whose mother was not blind marries a normal sighted woman who suffers from migraines but whose father did not. In what proportion of their children would you expect to have both aniridia and migraine to occur? __________ 7. A researcher believes, as a result of investigation,...

UESTION 4 Background info: in Labrador retrievers there is a gene, called black that participates in determining coat colour. This gene has two alleles, B and b. There are two other genes that participate in determining coat colour in Labs: the extension gene (with alleles E and e) and the agouti gene. All Labs are homozygous mutant for the agouti gene (so we can ignore this gene in our analyses and in our predictions, because it is not a variable)....

Consider a gene with a dominant and recessive allele in a population conforming to the Hardy-Weinberg conditions. Assuming the frequency of the recessive allele in the entire population is q, show that the frequency of the recessive allele in individuals with the dominant phenotype is q/(1+q).

In golden retrievers, the D/d gene codes for an enzyme that produces a pigment. The dominant allele (D) results in a golden pigment, while the recessive allele (d) codes for red pigment. Additionally, the V/v gene produces a transport protein responsible for depositing the pigment produced by D/d into the hair. When the dominant V allele is present, the color expressed by D/d will be deposited and the dog will be that color (golden or red). However, allele v is...

The HAIR gene (abbreviated as H) controls hair color with the dominant phenotype being dark brown hair and the recessive phenotype being blonde hair. The WIDOW gene (abbreviated as W) controls the presence of a ‘widows peak’ in the hairline (having a point at the center of the hairline). Having a widows peak is dominant and not having a widows peak is recessive. Gene H and Gene W are linked genes. Two individuals with the genotypes indicated below mate (note:...

Assume that for a given gene a mutation creates an allele that functions as a dominant negative. The gene codes for a protein that forms a tetramer (4) within the cell. If at least one of the subunits has the mutant structure the entire protein is inactivated. For a heterozygous individual, what percent of the tretramers present in the cell will be inactive?
