in cattle, coat color is controlled by codominant alleles. a red-coated cow (RR) is crossed with a white-coated bull (WW). what are the expected phenotypes of the offspring?

Question

a all red coat
b all white coat
c all pink coat
d red and white coat

Answer 1

In this scenario, you have a red-coated cow with the genotype RR and a white-coated bull with the genotype WW. Since coat color is controlled by codominant alleles, the offspring (which will have the genotype RW) will display a phenotype that is a blend of both parents' traits.

In this case, the RW genotype results in a pink coat because the red and white alleles are both expressed.

Therefore, the expected phenotype of the offspring is:

c. all pink coat
