Question
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?(1 point)ResponsesAll pink coatAll pink coatAll white coatAll white coatRed and white coatRed and white coatAll red coatAll red coat

In this case, the red-coated cow has the genotype RR (homozygous for red), and the white-coated bull has the genotype WW (homozygous for white). Since the alleles are codominant, when these two are crossed, the offspring will inherit one allele from each parent.
The possible genotypes of the offspring will be:
- From the cow (RR), the offspring can only inherit the R allele.
- From the bull (WW), the offspring can only inherit the W allele.
Thus, all offspring will have the genotype RW.
Because the alleles are codominant, the phenotype of the RW offspring will be a mix of both colors, resulting in a coat color that is red and white.
Therefore, the expected phenotypes of the offspring are:
**Red and white coat.**
