The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

Aa Aa Aa Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population ...

The equilibrium for a population with the alleles A and a, for example, would be allele frequencies of .6A and .4a and genotype frequencies of .36AA, .48Aa, and .16aa. By describing specific ideal ...
