Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and ...
Eastern Pennsylvania is home to beautiful farmlands and countryside, but it's also a gold mine of information for geneticists, who have studied the region's Amish culture for decades. Because of their ...
In a recent study posted to the bioRxiv* preprint server, researchers developed and validated an approach for the joint inference of measurement noise and genetic drift by analyzing time-series data ...
In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...
Urbanization is a global phenomenon with profound effects on the ecology and evolution of organisms. We examined the relative roles of natural selection, genetic drift and gene flow in influencing the ...
Residing in the hills of southern Thailand, the Maniq comprise one of the last hunter-gatherer communities in the world. Although the Maniq are geographically isolated, they share many cultural ...
Genetic drift and natural selection were analyzed in a genetically isolated Zapotec-speaking community in the Valley of Oaxaca, southern Mexico. Moderately intense genetic drift and selection ...
WEST LAFAYETTE, Ind. — Scientists have identified a new member on the genetic family tree of an endangered pupfish native to south-central New Mexico. “We went into this thinking that there was one ...
