What is gene flow?

• Movement of genes due to migration

• Selective breeding

• Reduction of gene variety due to a disaster

• Mutation creating new genes

Tags

NGSS.HS-LS4-2

How does natural selection influence the gene pool?

• By introducing new genes

• By favoring adaptations suited to the environment

• By removing all mutations

• By ensuring gene frequency does not change

• Higher resistance to cold

• Less susceptibility to sunburn

• Better camouflage

Why is natural selection unique among evolutionary processes?

• It doesn't change the gene pool

• It leads to adaptation

• It prevents mutations

• It ensures gene flow
