Genetic variation is stored in a population's gene poolâthe combined alleles of all of the individuals in a population. allele frequency An allele frequency is a measure of how common a certain allele is in the population.
Genetic variation refers to genetic differences both within and among populations. There may be multiple variants of any given gene in the human population (alleles), leading to polymorphism.he main cause is genetic drift, this is the effect of random changes in the gene pool. In humans, founder effect and past small population size (increasing the likelihood of genetic drift) may have had an important influence in neutral differences between populations.
