Environmental Science Quiz: 5-1

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

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

This mechanism of evolution occurs when individuals migrate between populations.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

Which of the following is an example of artificial selection?

• 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.

• Variation
• Adaptation
• Behavior
• Environment

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.
