Question

In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are

expected from a cross between two heterozygous shorthaired rabbits?

Answer 1

Genotype Phenotype

SS 1/4 Short hair 3/4

Ss 2/4 Short hair 3/4

ss 1/4 Long hair 1/4

Step-by-step explanation:

The resulting off-spring would have the following genotype and phenotype:

1 out of 4 will have a genotype of SS.

2 out of 4 or half will have a genotype of Ss.

1 out of 4 will have a genotype of ss.

But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:

Short hair: 1/4 + 2/4 = 3/4

Long hair: 1/4
