What describes when the best adapted individuals in a population survive to reproduce, passing on the favourable alleles that confer the selective advantage?

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

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.

What does variation within a population makes possible?

• for a population to evolve over time in response to changing environmental conditions

• for a population to breed over time in response to changing environmental conditions

• For a population to evolve over time in response to the same environmental conditions

• For a population to evolve over time in response to extreme environmental conditions

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
