Question

In mountain Koalas, brown coat color is recessive to gray coat color. A gray female rabbit gives birth to four gray-coated and three brown-coated baby rabbits. What can be deduced about the genotype of the baby rabbits’ father?

Answer 1

Answer:

gg

Explanation:

It is given that allele for brown colored coat is recessive to gray colored coat. Let the allele for brown color coat be represented by “g” and gray color coat be represented by “G”

Since brown color is a recessive trait. It will be present only in offspring having genotype “gg”. This means that genotype of both the parents will have “g” allele.

Since it is given that female is gray colored thus genotype of female would be “Gg”

So the father would have genotype “gg”
