(Questions 38-40] You have a large population (10,000 individuals) of a species of bird that is found along the mainland coastal region of a continent There is a single gene that is responsible for wing color in these birds, and there are three alleles at this locus. The alleles are for yelliow, blue, and red. The allele frequencies in the coastal region are 0.095, 0.46, and 0.445 respectively. There are three islands of similar size and habitat that are located an equal distance from the aforementioned mainland coastal region. At exactly the same time, three separate groups of 40 individuals leave the mainland coastal region and colonize each of the islands. Immediately after the colonization event, you determine the allele frequencies for each island population and find the following Island numberYellow allele frequency Blue allele frequency Red allele frequency 1 0.09 0.46 0.45 12 0.106 0.446 0.448 0.524 0.476 Genetic drift is the mechanism of evolution that most likely explains these results. Select one: True O False

There is a single gene that is responsible for wing color in these birds, and there are three alleles at this locus. The alleles are for yellow, blue, and red. The allele frequencies in the coastal region are 0.095, 0.46, and 0.445 respectively.

After some time, individuals begin to migrate between islands 2 and 3, but the overall population size remains at 40 individuals on each island. On island 3, you would expect that the red allele frequency will decrease, but the yellow and blue allele frequencies will increase over time. Select one: O True O False After many generations, you return and sample individuals from the mainland coastal region and island 2, and you discover that the same mutation, a green allele, has appeared in both populations. It is present in five individuals in the mainland population and in five individuals in the population from island 2. True or False? Mutation is a stronger evolutionary mechanism in the large mainland population than in the small island population. Select one: O True O False
