Question

Quizplus · Accepted Answer

The two primary components of the process of natural selection are variability (the existence of differences among individuals in a population) and competition (the struggle among individuals for limited resources). While survival of the fittest is often associated with natural selection, it is a consequence rather than a component of the process. Genetic recombination is another mechanism by which variation is generated but is not a component of natural selection itself. Sexuality and mortality are not directly involved in the process of natural selection.
