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. What is the probability of having a short-haired cat?
A) 0%
B) 25%
C) 50%
D) 75%
E) 100%

C) 50%

Explanation:

When crossed, a heter ozygous long-haired cat (Hh) and a hom ozygous short-haired cat (hh) produces 50% heter ozygous long-haired (Hh) and 50% hom ozygous short-haired (hh)

I would appreciate brainliest, if not that's ok!
