What are the two main ways we get different variations of genes?

A: mutations- changes in the DNA sequence.GENETIC RE-SHUFFLING - during the process of meiosis (making of sex cells) whole chromosomal regions of DNA can exchange genetic material.

B: shape of protein being disruptedOccurs when a protein unfolds

C: Evolution-Change of populations over timeDescent with Modification- results from changes in gene frequency which results in change of populations over time

D: Denaturation - destroys protein functioncannot return to original shape
