Evolution

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.

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.

In small populations, individuals that carry a particular allele may leave more descendants than other individuals, just by chance

• genetic flow

• genetic drift

• genetic trade
