When one or more of these forces are … WebbThe change in allele frequency due to genetic drift is greater if the population is too small. 5. Gene flow changes allele frequency due to mixing of new individuals in a population. As a result different alleles find their way into the population (like immigration) and these genes spread. Allele may be lost from the population through emigrations.
