What does variation of traits mean?

Genetic variation refers to differences in the genetic makeup of individuals in a population. Genetic variation is necessary in natural selection. In natural selection, organisms with environmentally selected traits are better able to adapt to the environment and pass on their genes.

Variation of traits means that half of the fathers traits and half of the mothers traits are put into the child. But if you are producing asexually then the child would have identical traits to whatever reproduced.
