The level of inbreeding is proportional to the FST value. (True or false)
Inbreeding attenuates heterozygosity. (True or false)
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?
In a population that is in HW equilibrium, 38% of individuals are recessive homozygotes for a certain trait. In a population of 14,500, calculate the percentage of homozygous dominant individuals and heterozygote individuals.

- A population in HW equillibrium is taken into the lab for an experiment in which inbreeding occurs. The inbreeding coefficient is 0.6.

The open circles show the average fitness of hypothetical 'mutant-free' individuals that have no deleterious alleles. The shaded circles show the average fitness of individuals produced by random mating. The dark circles show the average fitness of individuals with an Fof 0.25 (equivalent to full-sib matings). In the diagram on the right, imagine that 'before' refers to before genetic rescue has been instituted (that is, before managed gene flow into a small and isolated population). The circles are defined the same as above. Draw what the circles (unfilled, grey filling, and dark filling) would look like in the 'after' portion of the diagram, that is, after a single pulse of gene flow from a small number (~5) of translocated individuals, if fixed genetic load decreases in this population.…arrow_forwardThis type of experiment, where members of an outbred populations are introduced to an inbred population as mating partners, is sometimes called a “genetic rescue”.
