Answer

Answer:

B. RW

Explanation:

Step1: Define alleles

Let R represent the dominant allele for red and W represent the dominant allele for white.

Step2: Determine parental alleles

The red cow is homozygous dominant (RR) and the white cow is homozygous dominant (WW).

Step3: Use Punnett - square logic

When RR is crossed with WW, each parent can only contribute one type of allele. The red cow contributes R and the white cow contributes W. So the offspring will have the alleles RW.
