Lincoln Red cattle are entirely red. Hereford cattle have a white face. The white face is due to a dominant allele for which the 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 the cows but died of exhaustion before he had fertilized the whole herd. The farmer borrowed a neighbor's Hereford bull called Herbert, to finish Larry's job.  a.) When the calves were born, the farmer had found he could distinguish between Larry's and Herbert's offsprings. How? b.) 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?

Inheritance and Mendelian Genetics

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 biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
