HARDY-WEINBURG PRINCIPLE
... Genetic mutations create new alleles or change an existing one into another, thereby changing the frequency of both alleles. Gene duplications are the main source of new genetic material, as extra copies they are free to mutate with less likelihood of causing harm. Mutations occur as 1 in 10000 in a ...
