AP Biology Unit 7 Test Review

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 organism knew it needed that trait, survives, and passes it on.

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Where do adaptations come from?

• The individual organism decides to adapt

• Mutations that give an organism an advantage in its environment

• Genetic recombination during meiosis

• Both mutations and genetic recombination are sources of adaptation

• Evolution

• Selective Breeding

• Artificial Selection

Which best describes the role of mutations in natural selection?

• Mutations help an organism to better survive in their environment

• An organism may acquire a helpful mutation by interacting with the environment

• A mutation may result in a beneficial trait that makes an organism more likely to survive and reproduce

• Organisms with certain traits are more likely to win competitions for mutations

All rabbits of the same species living in a particular area would be an example of a(n)

• population

• species

• community

• ecosystem

The more genetic variation a population has,

the more likely it is for some individuals to

• evolve

• migrate

• survive

• mutate
