Genetic drift and gene flow in post-famine Ireland.
This study examines the genetic impact of the Great Famine (1846-1851) on the regional genetic structure of Ireland. The Great Famine resulted in a rapid decrease in population size throughout Ireland in a short period of time, increasing the possibility of genetic drift. Our study is based on migration and anthropometric data collected originally in the 1930s from 7211 adult Irish males. These...
متن کاملRandom Genetic Drift & Gene Fixation
Random Genetic Drift is one of the evolutionary forces that effects the distribution of alleles and changes their frequencies in populations. The main idea behind this theory is that genetic changes can happen randomly. This can be explained through the Bottleneck effect. There are two main factors that have an influence on genetic drift, the first one is the Effective Population Size Ne , whic...
متن کاملEffects of genetic drift and gene flow on the selective maintenance of genetic variation.
Explanations for the genetic variation ubiquitous in natural populations are often classified by the population-genetic processes they emphasize: natural selection or mutation and genetic drift. Here we investigate models that incorporate all three processes in a spatially structured population, using what we call a construction approach, simulating finite populations under selection that are b...
متن کاملDrift and Gene Flow in Shaping Spatial Patterns of Genetic Differentiation
21 Spatial patterns of neutral genetic diversity are often investigated to infer gene flow in wild populations. 22 However, teasing apart the influence of gene flow from the effect of genetic drift is challenging given that both 23 forces are acting simultaneously on patterns of genetic differentiation. Here, we tested the relevance of a 24 distance-based metric-based on estimates of effective ...
متن کاملRestricted gene flow and genetic drift in recently fragmented populations of an endangered steppe bird
Identifying the genetic processes derived from habitat fragmentation is critical for the conservation of endangered species. We conducted an integrated analysis of genetic patterns in the endangered Dupont’s lark (Chersophilus duponti), a circum-Mediterranean songbird threatened by the loss and fragmentation of natural steppes in recent decades. After sampling all the remaining Spanish populati...
