Question

Which of the following are characteristics of natural selection? Select three options.

1) It affects populations.
2) It occurs when there is genetic variation.
3) It selects organisms with certain traits to survive.
4) It affects only individuals.
5) It occurs when organisms are genetically identical.
6) It selects organisms at random to survive.

Answer 1

Natural selection affects populations, occurs when there is genetic variation, and selects organisms with certain traits to survive.

Step-by-step explanation:

The characteristics of natural selection are as follows:

1. It affects populations: Natural selection acts on a population level by favoring certain traits and influencing the allele frequencies in a population.
2. It occurs when there is genetic variation: Genetic variation is necessary for natural selection to occur because it provides the raw material for adaptation.
3. It selects organisms with certain traits to survive: Natural selection favors individuals with traits that provide an advantage for survival and reproduction, increasing their likelihood to pass on those traits to future generations.
