Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

Polydactyly is a rare dominant trait found frequently in people of African American
descent in which the hand has one or more extra fingers. A male with polydactyly,
who has a mother with non-polydactyly, moves to an island that is inhibited by
people who are not of African American descendant. Assuming that no other
African American immigrate to the island, calculate the probability that a great-
grandchild of this male will have polydactyly and briefly explain your answer.
(Hint: You may want to draw a pedigree to help you figure this out.)

Huntington disease is a rare dominant condition in humans that results in a slow but inexorable deteriorationof the nervous system. The disease shows what mightbe called age-dependent penetrance, which is to saythat the probability that a person with the Huntingtongenotype will express the phenotype varies with age.Assume that 50% of those inheriting the HD allele willexpress the symptoms by age 40. Susan is a 35-yearold woman whose father has Huntington disease. Shecurrently shows no symptoms. What is the probabilitythat Susan will show symptoms in five years?
