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

Genetic drift is likely to be seen in a population

• That has a low mutation rate
• In which natural selection is occurring
• That is very small
• For which environmental conditions are changing

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

• 0.80

• 0.04

• 0.32

• 0.64

The allele frequency of p = 0.20 What is the frequency of recessive genotype?

• 0.80

• 0.04

• 0.32

• 0.64
