You must draw a Punnett square and work out these problems to get the correct answers. In cats, long-hair (H) is dominant to short-hair (h). One cat is heterozygous for its long-hair and its mate has short-hair. First, use a Punnett square to determine the genotypes, phenotypes and probability of their possible offspring.

The correct answer is -

Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats

Explanation:

It is given that long hair is a dominant represented by H, over the short hair represented by h. In the cross of a heterozygous cat for long hair with a cat with short hair, would produce H, h and h, h gametes respectively.

Cross: Hh × hh

    H    h

h    Hh   hh

h   Hh   hh

In this Punnett, there are two heterozygous long hair offspring produced and two short-hair cats.

So, Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats
