change in the DNA sequence that leads to an advantageous outcome.

change in the DNA sequence.

Why is genetic variation among individuals beneficial?(1 point)

Genetic variation leads to more new traits in the population which means evolution can occur faster.

More genetic variation means higher rate of survival versus species that have less genetic variation.

Genetic variation staves off extinction because it creates a fit population.

Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.

What is the term used to describe having a trait that can be passed on to subsequent generations that increases the organism’s ability to survive in its environment and reproduce?(1 point)

natural selection

adaptation

fitness

genetic variation

What is the term used for genetic mutations that may result in neutral or even negative outcomes?(1 point)

genetic drift

artificial selection

genetic modification

natural selection

How are genetic modification and artificial selection similar?(1 point)

Both involve hybridization.

Both result from human influences.

Both result from natural selection.

Both involve crossbreeding.
