Which statement best describes Natural selection?
Which statement best describes Natural selection?

Differential survival and reproduction of individuals.
Environmental factor affecting survival.
Proposed evolution by natural selection.
13.
Natural selection means individuals with advantageous alleles are more likely to:

Survive and reproduce
Die young
Stop reproducing
14.

Natural selection acts on

genotypes directly only
phenotypes, changing allele frequencies in a population over time
individuals so that they change
species only
