In shorthorn cattle, coat colors are governed by a codominant pair of alleles R and W. The homozygous genotype RR produces red, the other homozygote produces white and the heterozygote produces roan ( a mixture of red and white). The presence of horns is produced by the homozygous recessive genotype pp and the polled condition by its dominant allele P.
If roan cows heterozygous for the horned gene are mated to a horned, roan bull, what phenotype ratio is expected in the offspring?
