Random Genetic Drift & Gene Fixation
نویسنده
چکیده
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 , which creates different genetic drift outcomes within different population sizes. The second factor that influences the rate of genetic drift is the selective advantage of a drifted allele. With these factors it is possible to calculate the time and probability of an allele fixation in any chosen population.

Nonadaptive processes in primate and human evolution.
Evolutionary biology has tended to focus on adaptive evolution by positive selection as the primum mobile of evolutionary trajectories in species while underestimating the importance of nonadaptive evolutionary processes. In this review, I describe evidence that suggests that primate and human evolution has been strongly influenced by nonadaptive processes, particularly random genetic drift and...
متن کاملMitochondrial DNA evolution in experimental populations of Drosophila subobscura.
When two mitochondrial DNA (mtDNA) haplotypes of Drosophila subobscura compete in experimental populations with discrete generations, one or the other approaches fixation, depending on the nuclear background with which they are associated. The approach to fixation, however, is strongly dependent on the effective number of females in the population, Nf. Whether or not the ultimate fate of a give...
متن کاملGene diversity and female philopatry.
The effect of female philopatry on the apportionment of gene diversity within a population is evaluated. Even with random mate selection, the apportionment of gene diversity within and among social lineages (groups of related females) is inherently different than in classically defined demic groups. Considerable excess heterozygosity occurs within lineages without substantial changes in total o...
متن کاملPerturbation expansions of multilocus fixation probabilities for frequency-dependent selection with applications to the Hill-Robertson effect and to the joint evolution of helping and punishment.
Natural populations are of finite size and organisms carry multilocus genotypes. There are, nevertheless, few results on multilocus models when both random genetic drift and natural selection affect the evolutionary dynamics. In this paper we describe a formalism to calculate systematic perturbation expansions of moments of allelic states around neutrality in populations of constant size. This ...
متن کاملComplete numerical solution of the diffusion equation of random genetic drift.
A numerical method is presented to solve the diffusion equation for the random genetic drift that occurs at a single unlinked locus with two alleles. The method was designed to conserve probability, and the resulting numerical solution represents a probability distribution whose total probability is unity. We describe solutions of the diffusion equation whose total probability is unity as compl...
