Biology 2- Lynsee Devers

What is Genetic Variation?

Genetic variation is the variation in genes and alleles.

It's important because it provides the genetic material for natural selection.

What are examples of Genetic Variation?

Some examples are:

Crossing over- when a leg of one chromatid and a leg of another chromatid break off, switch places, and reattach.

Independent assortment- it doesn't matter what way the chromatids are arranged, it is random and different for every chromatid.
