These findings demonstrate … WebKeywords: serial founder effect, admixture, gene flow ABSTRACT Objectives. Geneticists have argued that the linear decay in within-population genetic diversity with increasing geographic distance from East Africa is best explained by a phylogenetic process of founder effects, growth, and isolation termed serial founder effects (SFE). However ...

Web2 Feb 2012 · Atkinson argued that a survey of sound systems around the world supports the so-called serial founder effect (SFE) "in which successive population bottlenecks during range expansion progressively reduce diversity", just as a similar survey of human genetic and phenotypic diversity does. He also argued that the phonemic-diversity evidence … Web13 Sep 2011 · Our strategy is to test the fit of a serial founder effects process to the pattern of neutral autosomal genetic variation and to examine the contribution of gene flow and European admixture to departures from fit. The genetic data consist of 678 autosomal microsatellite loci assayed by Wang and colleagues in 530 individuals in 29 widely ... Serial founder effects have occurred when populations migrate over long distances. Such long-distance migrations typically involve relatively rapid movements followed by periods of settlement. The populations in each migration carry only a subset of the genetic diversity carried from previous migrations. As a result, … See more In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by See more The founder effect is a type of genetic drift, occurring when a small group in a population splinters off from the original population and … See more Due to various migrations throughout human history, founder effects are somewhat common among humans in different times and places.
