Which are characteristics of natural selection? check all that apply. it affects populations. it affects only individuals. it occurs when there is genetic variation. it occurs when organisms are genetically identical. it selects organisms with certain traits to survive. it selects organisms at random to survive.

1. It affects populations.

2. It occurs when there is genetic variation.

3.It selects organisms with certain traits to survive.

Natural selection is a natural phenomena, in which differential survival and reproduction occurs, which means that some organisms have phenotypic traits which favors their survival and reproduction in the changing environment over others.

1. The phenomena affects the population as the population with beneficial traits have better chances of survival over others.

2. Some genetic variations are beneficial which makes the organism different from others with respect to survival in the changing environment.

3. It selects the organisms with certain traits to survive this can be explained by an example of two beetle populations of red and green color. The green color beetles  resembling the color of grass, remains undetected by the crow population, survive and grow in number, whereas the red beetle detected and eaten by the crow population.
