Piebaldism is a skin condition that causes an infant to be born with white birthmarks due to a genetic mutation. It is an autosomal dominant trait. A woman with piebaldism married a man without it. They have three daughters, two of whom also have piebaldism. One of their piebald daughters married a man who also has piebaldism and they have two sons with piebaldism, one son without it and one daughter with it. Draw the pedigree for this family and fill in as many of their genotypes as you can.

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.
