What can cause variation within a species?

Reproduction produces variation in population gene pools. Every time organisms reproduce, be this sexually or asexually, the genome of the offspring is slightly offset compared to that of its parent(s). Additional factors in this may be mutagenic influences in the environment, such as radiation.

How does variation work in natural selection?

Answer 1If you have group of a species with dark skin and another group with light skin in an environment with much direct sunlight, the dark skinned gene group will be selected as the dark skin (with more melanin) is protective in that sunlit environment. If the environment is northern, the lighter skin gene will become more common. This variation will be a help in natural selection.Answer 2Genetic variation, or reproductive variation, are the mechanisms that cause one sibling to be slightly different from another. It is this difference that allows natural selection to work, for there may be various reasons, to do with these differences, why one sibling is more successful in producing offspring than the other.
