Genetic Drift and Gene Flow Quiz

This mechanism of evolution occurs when individuals migrate between populations.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

Genetic drift is change in the allele frequency of a population due to...

• random chance
• natural selection
• non-random mating (sexual selection)
• artificial selection

Which of the following is an example of the bottle neck effect?

• Bald Eagles are hunted until near extinction, population recovers.
• Small group of iguanas floats to an island, starts a new population.
• Red fox pups are more likely to survive in a snowy environment if they are born white.
• Farmer chooses seeds from largest apples to plant next year.  This results in larger apples from year to year.

Five hundred years after the deer had established a flourishing population in the park, a few of them venture to a wooded area with other deer and have babies with the deer there.
