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 ...

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 ...

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 ...

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 ...

Chaotic genetic patchiness denotes unexpected patterns of genetic differentiation that are observed at a fine scale and are not stable in time. These patterns have been described in marine species ...

A groundbreaking DNA study, published this week, suggests that the first humans to reach the ancient landmass called Sahul – ...

A new genetic study has found Indigenous Australians travelled over two distinct routes, and 100 kilometres of open water, to ...

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 ...
