Natural Selection Review

1. The process of choosing parent organisms for desired characteristics is called

• natural selection

• Artificial selection

• random selection

• genetic manipulation

Which statement is true comparing natural selection and artificial selection?

• In natural selection, traits benefit humans and in artificial selection, the traits benefit the species

• In natural selection, traits benefit the species and in artificial selection, the traits benefit humans

• In natural and artificial selection, the process takes hundreds of years to occur

• In natural and artificial selection, nature determines what traits will be passed down to offspring.

Changes in a species over generations, due to changes in the environment

• Distribution

• Mutation

• Adaptation

• Resistance

Suppose white rabbits and black rabbits live in the same environment where birds are predators. The environment is very snowy and there is plenty of food for both rabbits. One rabbit however is better adapted for this environment. According to the theory of natural selection what will most likely happen to the rabbits?

• White rabbits will be favored to survive due to camouflage, so black rabbits will most to a place without white rabbits.

• The white rabbit population will likely increase but the black rabbits will decrease in population until they possibly go extinct.

• Both rabbit populations will increase because they will adapt by changing color.

• The black rabbit population will likely increase but the white rabbits will decrease and possibly go extinct.

Starlings produce an average of five eggs. If there are more than five the parents cannot adequately feed the young. Fewer than five and predators may destroy them. As a result, five eggs becomes the most common number.

• Stabilizing

• Directional

• Disruptive
