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 ...

I draw from the concept of “gene flow,” which refers to genetic material flowing from one place to another, contributing to the variety of life that makes our planet so exciting. Gene flow ...

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 ...

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 ...

But there were also some big surprises: "When we started getting results from our analyses of gene flow between different giraffe lineages, we had to check twice," says Laura D. Bertola ...

The majority are in the very early preclinical stage of development, but applications for regulatory approval have been ...

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 ...

Under normal conditions, genes in a given population are exchanged through breeding, so that even if some variation occurs, it is limited by this "gene flow." But gene flow is interrupted if the ...
