1

If a mutation introduces a new skin color in a lizard population, which factor might determine whether the frequency of the new allele will increase?

A storm blows through an area full of finches, and out of a population of 10,000 finches, 12 are blown by the storm onto a remote island. Why would the 12 finches on the island have a different gene pool than the large population of finches that they came from?

They were all small beaked finches feeding on small seeds

They have less genetic diversity that the large finch population

They started reproducing after they arrived at the island

Required

1

The geographic isolation of two populations of a species tends to increase differences between their gene pools because it:

increases differences in courtship behavior

prevents interbreeding within each community 

Required

1

Although they often live in the same habitat, the American toad breeds earlier in the spring than the Fowler’s toad does. What can be inferred from this information?

The two species do not interbreed because of temporal isolation.
