They identify things such as hair colour, skin tone, eye colour and blood type; Quite simply, the many genetic qualities that range among people today. Genetic drift isn't going to introduce new alleles to the populace, nevertheless it can cut down variation inside a population by taking away an allele from your gene pool.
