Question

In cats, long hair is recessive to short hair. A homozygous short haired male (HH) is marred to a long haired female (hh). What possible phenotypes could their kittens have?

Answer 1

Long hair (h) is recessive, short hair (H) dominant. Cross HH (male) × hh (female) gives all offspring Hh. Phenotype: all kittens will be short-haired (but all are carriers of the long-hair allele).
