Question

Genetics

You are studying a population of snowshoe hare living in Yellowstone National Park. For camouflage, the hare's fur turns white during the winter and rusty brown during the summer. You sequence a transcription factor gene involved with regulating the fur color change. There are two alleles, A1 and A2, and three phenotypes: early change, intermediate change, and late change of fur color.  In your studies, you notice that changing fur color too early or too late leads to easy detection by predators. You observe frequencies of 42, 56, and 21 individuals for genotypes A1A1, A1A2, and A2A2, respectively. Test for Hardy-Weinberg equilibrium and draw appropriate conclusions about evolutionary forces acting on the population.

Answer 1

Please look in the image for solution:

Evolutionary forces are:

* No selection because the population is in Hardy Weinberg equilibrium.

* No mutation, no migration because population is ideal. Because it is Hardy Weinberg equilibrium.
