genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
Sickle cell
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.

No, there is no genetic variation upon which natural selection can operate.
Genetics refers to the study of genes, the microscopic biological building blocks that make us what we are. Used in a sentence: "The study of genetics is helping us to learn why certain diseases run in families."
Genetic crossover occurs, which causes a sharing and transference of genetic information between maternal and paternal copies of chromosomes and further enhances the genetic variability of their offspring.
Human recombination is a significant source of genetic variation.
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.
Sickle cell
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
No, natural selection works on that genetic variation presented to it.
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.
