Cats have a gene that codes for the color of their fur.
suppose that a certain breed of cat can have black, gray, or white fur. black fur is dominant, white fur is recessive, and gray fur is intermediate (i. e., cats with gray fur possess one allele for black fur and one for white fur).
if a gray cat and a white cat have kittens, what phenotypes could the kittens exhibit?
a) gray or white fur
b) only gray fur
c) black or white fur
d) black, gray, or white fur
