What are ways species exchange genes with each other? Hybridization and gene flow are shortcuts to biodiversity that don’t always involve differentiation. By continuing to study hybridizing ...

Aa Aa Aa Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population ...

What keeps a species coherent over time? "Gene flow" between the different populations of a species is one main explanation. Because members of a species usually interbreed only amongst themselves ...

However, the study also revealed some unexpected findings: When we started getting results from our analyses of gene flow between different giraffe lineages, we had to check twice. The results ...

They assessed sharing of segments, inferred gene flow, and looked at variation to identify candidates for positive and negative selection. The study of ancient DNA has greatly advanced our ...

Ancient DNA research suggests that our non-African ancestors mixed with Neandertals about 50,000 years ago, resulting in one to two percent Neandertal DNA in non-African modern humans. In a study ...
