Problem #4 In cattle, coat color is controlled by two codominant alleles. One allele produces a red coat, (R), and one produces a white coat, (W). A cow with heterozygous alleles will have a roan coat. In the same breed of cattle, not having horns, (N), is completely dominant over the presence of horns, (n). What phenotypes and genotypes would be expected from a cross between a roan, horned bull and a hornless, red cow that is a carrier for the horned allele?

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain b…
