What is the term for the success of an organism in passing on its genes to offspring, relative to the other members of its population?

Darwinian fitness (correct)

Natural selection

Genetic drift

Relative fitness

What is the primary mechanism by which genetic variation is generated during sexual reproduction?

Gene flow

Meiosis and fertilization (correct)

Mutation
