if a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), what alleles will the…

Brief Explanations:

Let's assume the allele for red is R and for white is W. A homozygous dominant red cow has genotype RR and a homozygous dominant white cow has genotype WW. When they are crossed, each parent can only pass on one type of allele. The red - cow will pass on R and the white - cow will pass on W. So the offspring will have the genotype RW.

Answer:

B. RW
