In the year 2500, five male space colonists and five female space colonists (all unrelated to each other) settle on an uninhabited Earthlike planet in the Andromeda galaxy. The colonists and their offspring randomly mate for generations. All
ten of the original colonists had free earlobes, and two were heterozygous for that trait. The allele for free earlobes is
dominant to the allele for attached earlobes.

Which of these is closest to the allele frequency in the founding population?
A) 0.4 a, 0.6 A

B) 0.5 a, 0.5 A

C) 0.2 a, 0.8 A

D) 0.8 a, 0.2 A

E) 0.1 a, 0.9 A

(please explain)

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution
