Working with the definitions of penetrance and expressivity, analyze the following pedigree and assume that the father of the proband is homozygous for a rare trait. (Consider a rare trait here to be less than 1 in 30,000.) What pattern of inheritance other than autosomal recessive could explain this pedigree? In particular, explain the genotype and phenotype of the proband (arrow).

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.
