Random 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 کاملDifferences in Genetic Structure among Fagus orientalis Lipsky (Oriental Beech) Populations under Different Management Conditions: Implications for in situ Gene Conservation
Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...
متن کاملGenetic variation and random drift in autotetraploid populations.
The rate of decay of genetic variation is determined for randomly mating autotetraploid populations of finite size, and the equilibrium homozygosity under mutation and random drift is calculated. It is shown that heterozygosity is lost at a slower rate than in diploid populations, and that the equilibrium heterozygosity with mutation and random drift is higher than for diploids. Outcrossing pop...
متن کاملGenetic Drift in Populations of Distorting Gene Complexes
We use stochastic population models to study the evolution of distorting gene complexes. Distorting gene complexes, or distorters, are chromosomal regions characterized by meiotic drive: a heterozygote bearing the distorter passes it to more than 50% of offspring. Homozygotes bearing the distorting complex are sterile. Although distorters promote themselves at the expense of other genes in the ...
