A population of 18 frogs has the following number of frogs of different genotypes:  AA = 6, Aa = 7, aa = 5, What is the frequency of the A allele in the population?

 In what kind of populations do we tend to see genetic drift working most quickly (the least number of generations)?

In a population of birds on an isolated island, it is found that females have a strong preference for mating with males based upon their appearance – resulting in fierce competitions, showy feathers, and creative displays by the males.  Is this population in Hardy-Weinberg equilibrium?

You are given the following information about a population: There are two alleles, C and c C is dominant to c C codes for blue hair and c codes for white hair The frequency of the c allele is 0.4 The population is comprised of 100 individuals. Assuming the population is in Hardy-Weinberg equilibrium, how many individuals have blue hair?

In a population of frogs, the following is the starting allele frequency: A1 A2 A3 A4 0.19 0.30 0.01 0.50 Which allele is most likely to go to fixation (that is, to be the last allele remaining in the population)?

 Which of the following were modified through artificial selection by humans?

You are studying a population of kingfishers in Jamaica.  In 2019 you estimate the population to be 8754 and in 2020 you estimate that the population is 9310.  Calculate r for this group of beetles.

In Lake Michigan, Isle Royale currently has a population of 30 wolves and 840 moose.  If the pack’s population grows logistically, how many wolves will there be in the next year?  Assume a growth rate, r = 0.1 and a carrying capacity of 40 wolves.  You are potentially allowed to have fractions of wolves for the purpose of calculation.

What is the most likely ecological consequence of losing a keystone species from an ecosystem?

In Lake Michigan, Isle Royale currently has a population of 30 wolves and 840 moose.  If the pack’s population grows logistically, how many wolves will there be in the next year?  Assume a growth rate, r = 0.2 and a carrying capacity of 40 wolves.  You are potentially allowed to have fractions of wolves for the purpose of calculation.
