NGSS.MS-LS4-4

The process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variation.

• Evolution

• natural selection

• adaptation

• extinction

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.
