Lab Name: Subject: Date of Submission: Abstract Migration modifies genetic drift because it could increase the allele frequency within a population. Understanding the effect of migration on genetic drift is important to the genetics profession because it helps the professionals to appreciate the effect of migration on natural selection. It is why the researcher conducted a study with an aim of identifying the effect of migration on genetic drift. Specifically, the researcher examined black, brown and white-winged moths.. The results indicated that migration modifies the effect of genetic drift because of its effect on allele frequency. Keywords: Migration, genetic drift. Introduction Migration could be elucidated as the movement of organisms from one place to another.
