Question

In cats having hair is dominant (H) over not having hair (h). If a male cat that is heterozygous for hair is crossed with a hairless cat what are the genotypes and phenotypes that their offspring may have? Answer using ratios

Answer 1

A heterozygous cat has a genotype Hh
A hairless cat has a genotype hh
When crossed, the results could be any of the following:
Hh (with hair)
hh (hairless)
There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.
