WebWe can divide the number of copies of each allele by the total number of copies to get the allele frequency. By convention, when there are just two alleles for a gene in a population, their frequencies are given the symbols p p and q q: p = \text {frequency of}\: W p = frequency ofW = = 13/18 13/18 = = 0.72 0.72, or 72\% 72%.

WebGenetic drift is a random change in allele frequency brought on by errors in random sampling. The transfer of alleles from one population to another through interbreeding or migration is known as genetic flow.
