In guinea pigs, black dominates over white. What offspring can be expected from black

In guinea pigs, black dominates over white. What offspring can be expected from black and white homozygotes? Describe the genotypes and phenotypes of all individuals.

Let’s designate the gene that causes the development of black hair in guinea pigs as C, then the gene for white wool in these animals will be written as c.

Guinea pigs with black coats that are homozygous for the condition will be CC. They will produce C.

Guinea pigs with white coats are also homozygous. Let’s write them down as ss, the sex cells they produce as c.

All offspring that can be obtained from crossing the described guinea pigs with each other will be the same: heterozygotes with black fur (Cc).

Answer: black animals are homozygotes for the dominant trait (CC), white guinea pigs are homozygotes for the recessive trait (cc), cubs are heterozygotes (Cc) with black fur.
