2. If a population experiences no migration, is very large, has no mutations, has random mating, and there is no selection, which of the following would you predict?

The population will evolve, but much more slowly than normal.

The makeup of the population's gene pool will remain virtually the same as long as these conditions hold.

The composition of the population's gene pool will change slowly in a predictable manner.

Dominant alleles in the population's gene pool will slowly increase in frequency while recessive alleles will decrease.

The population probably has an equal frequency of A and a alleles.

In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh-positive phenotype is produced by a dominant gene (A), and the Rh-negative phenotype is due to its recessive allele (a), what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive?
