Short Hair Dominance in Cats

What would be the genotype(s) of a cat with long hair?

A) SS or Ss

B) ss

C) Ss

D) SS

Answer:

A, C, D

In cats, short hair (S) is dominant to long hair (s). This means that a cat with long hair must have the genotype ss. Therefore, the possible genotypes for a cat with long hair are SS or Ss. Both SS and Ss can produce long-haired cats when the dominant S allele is not present.

So, if a cat has long hair, its genotype can be SS, Ss, or ss. This is because the recessive trait for long hair (s) can only be expressed in cats with the genotype ss.
