Population geneticists study what aspects of a population?
Select one:
a. Genetic variation
b. Allele frequencies
c. Genotype frequencies
d. All of these choices are correct
Homework Answers
d. All of these choices are correct
Population genetics is the study of genetic variation within and among populations. It is performed by changes in the frequencies of genes and alleles in populations over space and time. The relationship can be explained well by Hrdy Weinberg law which works when population size is large, mating is random, and mutation, selection and migration are negligible.

In a population of jaguars, a gene with two alleles encodes the fur color. Allele B causes melanism (dark fur) and is dominant over allele b, which results in light colored fur. There has been a rare immigration event into a population of jaguars under study, resulting in the following genotype frequencies: 60% BB, 20% Bb and 20% bb individuals. If we assume HardyWeinberg equilibrium for future generations, what would be the genotype frequencies after 5 generations?
