genes are kept in chromosomes, there is this thing called meiosis which is when the chromosomes/genes get split in half, one from both parents that way it equals the normal amount of genes later. the genes have tons of ways to mix and match around while getting split apart and then ending up in the same place.
Genetic variation is one of the conditions required for Natural Selection to occur.
A large population increases genetics variation. Mutation will also increase genetics variation.
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
Meiosis is responsible for genetic variation
If a population dwindles, there is low genetic variation and a species may risk extinction.
mutations cause genetic variation, and vice-versa. If there is a genetic variation (or lack of one), then this can effect the severity of the mutation.
Yes, the independent assortment of genes during meiosis does cause genetic variation.
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
genetic factors
A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.

Sexual Reproduction Genetic mutation
Loss of genetic variation(:Novanet:)
Genetic variation can increase a population's adaptability to changing environments, enhance resistance to diseases, and contribute to overall biodiversity. However, high levels of genetic variation can also lead to increased risk of certain genetic disorders and diseases, as well as reduced fitness due to inbreeding.
Human recombination is a significant source of genetic variation.
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.
No, natural selection works on that genetic variation presented to it.
