People with polydactyly have more than five fingers or toes on their hands or feet. Polydactyly results from an autosomal dominant genetic disorder. Draw a pedigree for a family with polydactyly, using the following information:  Zack has polydactyly but his wife, Zoe does not.  Zack and Zoe’s daughter Yolanda has polydactyly but their son Yogi does not.  Yolanda has two children with her husband, Xavier, who does not have polydactyly:  Wilma, who is normal and Wade, who has polydactyly.  Use your pedigree to determine what is Zoe's genotype. A) DD B)dd C)Dd

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.
