Question - In certain cattle, hair color can be red (RR), white (WW) or roan (RW-a mixture of both red and white hairs). What exception to Mendel does this demonstrate?
a. When a red bull is mated to a white cow, what genotype(s) and phenotype(s) of offspring are possible?
b. If one of these offspring was mated to a white cow, what genotype(s) and phenotype(s) of offspring could be produced? What would be the phenotypic ratio?
