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. This makes them better able to sneak up on prey.
a) Give two reasons that the wolf population is not at Hardy-Weinberg equilibrium.
b)Which type of wolf is selected for in this new ecosystem?
c)How will the allele frequency change in the wolf population?
d) Is this an example of natural selection? Explain.
