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

The Hardy-Weinberg Model is...

• available at local hobby stores and retailers throughout the Greater Tazewell area.
• a mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.
• always occurring within individual organisms in nature.
• only useful in the lab and cannot be practically applied to real-world populations of organisms.
