What is Genetic Variation?
Genetic variation is the variation among genes and alleles.
An example of genetic variation is crossing over, when a leg from a chromatid breaks off and reattaches to the other chromatid in a tetrad.
Examples and Sources
An example of genetic variation is color, like hair color, and eye color. Based on the dominate gene you get from your parents, you will have that eye color, or hair color.
Tere are three sexual sources of variation; natural selection, crossing over, and independent assortment, which is random assortment of chromatids.
