If a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), what alleles will the offspring have? RW RW rW rw

In this scenario, you seem to be mixing up the genotypes of the cows. A red cow that is homozygous dominant would be represented as "RR" and a white cow is typically homozygous recessive, so it would be "rr". When these two are crossed (RR x rr), all the offspring will be heterozygous, "Rr", which means they will inherit one red allele from the red cow and one white allele from the white cow. Thus, all offspring will be phenotypically red due to the dominance of the red allele. If you're trying to emphasize a different genetic scenario, the alleles listed (like RW, rW, etc.) suggest you're working with multiple contributions. Just remember, in simple dominant-recessive systems, the dominant trait always overshadows the recessive one!
