Question 4

A population of wolves migrates north in search of food. As the wolves travel, they enter a region that has long, snowy winters. Some of the wolves have an allele that gives them white coats, making them better able to sneak up on prey.

a) Give two reasons that the wolf population is not at Hardy-Weinberg equilibrium. (6 points)

b) Which type of wolf is selected for in this new ecosystem? (3 points)

c) How will the coat color allele frequency change in the wolf population over time? (3 points)

d) Is this an example of natural selection? Explain. (4 points)

e) Has genetic diversity helped or hurt the survival of the wolf population? Explain. (4 points)

Answer :

Final answer:

The wolf population is not in Hardy-Weinberg equilibrium due to natural selection and gene flow. The white coat allele is selected for in the new ecosystem, and its frequency will increase over time. This is an example of natural selection where genetic diversity helps the survival of the wolf population.


Explanation:

a) The population of wolves is not in Hardy-Weinberg equilibrium because of two reasons. Firstly, the presence of white-coat alleles makes certain wolves better suited to survive in the snowy environment, which creates natural selection. Secondly, the migration of wolves to the new region introduces gene flow into the population.

b) In this new ecosystem, the wolves with the white coat allele are selected for, as it provides an advantage in sneaking up on prey.

c) Over time, the coat color allele frequency will increase in the wolf population due to natural selection favoring the white coat allele.

d) This is an example of natural selection because the advantageous white coat allele is being selected for in the new environment.

e) Genetic diversity has helped the survival of the wolf population as the presence of the white coat allele increases their chance of capturing prey, which in turn improves their survival.
