NGSS.HS-LS4-4

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection
• artificial selection
• inbreeding
• outbreeding

NGSS.HS-LS4-4

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.

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
