Question

Lincoln Red cattle are entirely red. Hereford cattle have a white face. The white face is due to a dominant allele for which Hereford breed is homozygous. A farmer has a herd of Lincoln Red cows and Larry, a Lincoln Red bull. Larry was allowed to mate with cows but died of exhaustion before he had fertilized the whole herd. The farmer borrowed a neighbour’s Hereford bull called Herbert to finish Larry’s job.

When the calves were born, the farmer found he could distinguish between Larry’s and Herbert’s offspring. How?
He kept one of Herbert’s male offspring to replace Larry. When this bull was mated to the Lincoln Red cows, what would be the phenotypes of the calves and in what proportions?
