In cattle, Horned (H) is completely dominant over the hornless (h) condition. A horned bull is bred to two cows. With cow A, which is hornless, a horned calf is produced. With cow B, also hornless, a hornless calf is produced. What are the genotypes of the bull and the two cows?

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.
