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.

The genotype frequencies are BB = 0.50, Bb = 0.37, and bb = 0.13. Do these numbers suggest inbreeding?

- This type of experiment, where members of an outbred populations are introduced to an inbred population as mating partners, is sometimes called a “genetic rescue”. How might measuring the average heterozygosity at a number of loci in the Swedish snake population allow you to test whether the introduced snakes had actually bred successfully with the inbred Swedish snakes?arrow_forwardA population in HW equillibrium is taken into the lab for an experiment in which inbreeding occurs. The inbreeding coefficient is 0.6. The original population is genotyped to determine the alleles present at the A locus, and the following frequencies of the three genotypes is observed: AA 0.49 Aa 0.42 aa 0.09 What is the expected frequency of aa individuals in the next generation? A. 0.258 B. 0.216 C. 0.09 D. 0.184arrow_forwardGrouse in Russia show a recessive mutation “short-tail” that causes problems in the control of direction when flying. In 2002 a survey of a large, freely interbreeding, population of 1,856 grouse revealed 142 with short tail feathers. Due to rising affluence there was an increase in recreational grouse hunting. In a later survey of the grouse over some years it was found that a significant decrease had taken place in the population. In 2003 there were 2,861 grouse and in 2004 there were only 2,369 and all the surviving grouse had long tails. Support by calculation that this change would reflect greater vulnerability of short tail grouse to killing by hunters.arrow_forward
