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.

Imagine that a population of pythons in Florida grew from 30,000 to 36,000 from 2018 to 2020.  What would be the per capita annual growth rate, r?

The Biological Species Concept emphasizes that:

How does poor energy transmission across trophic levels likely contribute to many top-level predators’ normally high endangerment status? Only ONE response option should be chosen.

Which of the following would be a crucial clue when identifying X-linked recessive disorders in a family’s genetic pedigree?
