In rats, hair color is either gray (G), black (g), or white. The white color is
produced due to an epistatic recessive allele of gene "a". In other words,
in order for the black or gray color to show up, the rat must have at least
one dominant (A) epistatic allele.
Two heterozygous Gray rats are crossed. Both rats are also heterozygous
for the epistatic gene.
Predict the probability that an offspring of this cross will:
a. Express the gray phenotype
b. Express the black phenotype
c. Express the white phenotype
**Be sure to express each answer as a percentage!
For this problem, you will need to upload a document containing the
following:
1. Complete the punnett square for this cross
2. Calculate the "chance"/probability of male offspring with the disease.
3. Clearly state your answer.
