Allopatric Speciation or/and Sympatric Speciation! :)
You should move this question to Mathematics instead. Or at least physics.
Genetic variation describes the genetic differences among individuals of the same species that are naturally occurring. <span>Each genotype within a population usually has different degrees of fitness to an environment. Mating between same species with favored genes guarantees survival of the population in their chosen environment. As the environment changes, the mating behavior between species may again change resulting to a different gene pool to guarantee survival. </span>
Each individual has a unique DNA sequence, with the exception of identical twins
