Question

Threatened species often have small, isolated populations where mating between relatives occurs. Let's assume one of these threatened species has a disease controlled by a gene that has two alleles A and a. Only individuals with two copies of the "a" allele have the disease and die before reproducing.

Question:

What are the effects of inbreeding on the frequency of the "a" allele, and the frequency of the disease in the population?

Expert Solution

Step 1: Inbreeding

When two ancestrally unrelated species mate and produce offspring it is known as inbreeding. The word "inbred" refers to the progeny of such a relationship.
