What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

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

• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

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

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
