Independent assortment of chromosomes, crossing over and Random fetiliztion
The three types of variation are genetic variation, environmental variation, and genotype-environment interaction. Genetic variation refers to differences in DNA sequences among individuals, while environmental variation is differences in traits caused by external factors. Genotype-environment interaction occurs when the effect of genes on traits depends on the environment.
The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.
Mechanisms such as gene flow, mutation, genetic drift, and natural selection are all considered mechanisms for genetic variation. Non-genetic mechanisms, such as Lamarckian inheritance or acquired characteristics, are not considered valid mechanisms for genetic variation in the traditional sense.
Genetic variation after meiosis is significant because it leads to the creation of unique offspring with diverse traits. This variation is important for evolution and adaptation to changing environments.
Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.

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.
There are three ways: a table, a graph, and an equation.
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.
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.

Genetic variation is one of the conditions required for Natural Selection to occur.
