Imagine a huge population with a gene that has ten functionally equivalent, neutral alleles. A small but genetically representative group of individuals from the big population is transported to an island, forming a small population. Which of the statements below best describes what will likely happen over time, and why? a. Because natural selection doesn't act on neutral alleles, the frequencies in the two populations should remain the same over time. b. Genetic drift will cause one allele to first become fixed in the island population, and later to become fixed in the original, large population. c. Genetic drift will result in the allele frequencies of the two populations diverging over time, with alleles being lost sooner in the island population. d. The allele frequencies of the two populations will change similarly due to a combination of genetic drift natural selection.
