A spotted cat with curled ears mates with a monochromatic cat with erect ears – the cat had 7 kittens

A spotted cat with curled ears mates with a monochromatic cat with erect ears – the cat had 7 kittens: 6 spotted and 1 monochromatic, all kittens have curled ears. What traits will be dominant? Determine the genotypes of parents and offspring?

The dominant features are spotted and bent ears, since all kittens in the first generation have bent ears and almost all kittens (3/4 offspring) are spotted.

The genotypes of the parents will be as follows:

Cat – СсDD, female – ccdd.

C – spotting, c – monochrome, D – bent ears, d – erect ears.

When mating, the offspring can only have the following genotypes:

CcDd is a spotted kitten with curled ears.

ccDd is a monochrome kitten with curled ears.

Answer: genotypes of parents: male – СсDD, female – ccdd; offspring genotypes: CcDd, ccDd.
