A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

• Genetic Drift
• Natural Selection
• Non-random mating
• Mutation

In the Hardy-Weinberg Equation, q² is the frequency of what?

• The recessive allele 
• the dominant allele
• the recessive genotype
• the dominant genotype

A population of 150 individuals has an allele frequency of 0.3 for the dominant allele (B) and a frequency of 0.7 for the recessive allele (b). Use the Hardy-Weinberg equation to determine the frequency of the genotype (bb).

• 0.09
• 0.42
• 0.49
• 0.21

Gene flow involves

• Natural disasters killing most of the members of a population
• Individuals moving into and out of the population
• Selective mating
• Small changes because of the environment

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.
