Wooly hair is a rare dominant trait found in people of Scandinavian descent in which the hair resembles the wool of a sheep. Amale with wooly hair, who has a mother with straight hair, movesto an island that is inhabited by people who are not of Scandinavian descent. Assuming that no other Scandinavians immigrate tothe island, what is the probability that a great-grandchild of thismale will have wooly hair? (Hint: You may want to draw a pedigree to help you figure this out.) If this wooly-haired male haseight great-grandchildren, what is the probability that one out ofeight will have wooly hair?

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.
