Question

Morgan breeds and sells snakes. He knows that he can make the most money by breeding and selling albino snakes. Albinism is a recessive trait. His female albino corn snake just produced six offspring. Two displayed normal coloration and four were albino. What do you know about the genotype of the father?

Answer 1

Answer:

Genotype of the father: Heterozygous dominant  (Aa)

Explanation:

Let's suppose allele "a" is responsible for albinism while allele "A" gives normal phenotype.

Given that Albinism is a recessive trait, it will be expressed in a homozygous recessive genotype only. The female snake is albino and hence, her genotype is= "aa".

Since the progeny have both normal and albino snake, the male parent should be heterozygous dominant (Aa) with one copy of normal allele and one copy of recessive allele.
