Genetic shift vs genetic drift
WebThe type (Genetic Drift) refers to an event in which the allele frequency of a population changes. The subtypes, Bottlenecking and Founder effect, are two different concepts. … WebDespite substantial advances in genotyping techniques and massively accumulated data over the past half century, a uniform measurement of neutral genetic diversity derived by different molecular markers across a wide taxonomical range has not yet been formulated. We collected genetic diversity data on seed plants derived by AFLP, allozyme, ISSR, …
