WebInterbreeding between the species can cause a 'swamping' of the rarer species' gene pool, creating hybrids that supplant the native stock. This is a direct result of evolutionary forces such as natural selection, as well as genetic drift, which lead to the increasing prevalence of advantageous traits and homogenization. Webgenetic drift, also called genetic sampling error or Sewall Wright effect, a change in the gene pool of a small population that takes place strictly by chance. Genetic drift can result in …

WebThis genetic drift can lead to changes in allelic frequency in a gene pool (modification) which will then be passed on to future generations (decent). Changing the allelic frequencies of a population is evolution. Students should predict that the smaller sample size will have a greater influence.

WebGenetic drift shows that evolution (more commonly microevolution) can take place by chance which may be due to natural selection or some other evolutionary mechanism. Genetic drift is a mechanism of evolution that produces random changes in allele frequencies in a population over time rather than selection-driven. WebWe rarely found evidence for parallel changes in orthologous genes in the intraspecific comparisons, but in some cases we identified changes in members of the same gene family. Using among-species comparisons, we detected positive selection in 0.003-0.69% and 2.4-7.8% of the genes using site and stochastic branch-site models, respectively.
