Question

A heterozygous white rabbit is crossed with a black rabbit. What is the probability of getting black rabbit offspring?

Answer 1

Answer:

1/2 or 50%

Explanation:

From the illustration, we will logically assume that the white allele is dominant over the black allele. Let us also assume that the white allele is represented by A, the alternate black allele will be a.

The heterozygous white rabbit will have the genotype Aa.

The black rabbit will have the genotype aa.

Crossing the two rabbits together:

               Aa    x    aa

            Aa   Aa   aa   aa

1/2 Aa - white color

1/2 aa - black color

Hence, the probability of getting a black rabbit offspring is 1/2 or 50%
