“This is because decreasing a population’s size causes its gene pool to shrink too.” Genetic diversity allows species to ...

A new study published in Nature Microbiology has uncovered significant genetic and antigenic diversity among H9N2 avian ...

Healthy populations tend to have a large gene pool with many genetic variants circulating. But the path to extinction erodes genetic diversity, because a species’ gene pool shrinks as the population ...

In effect, a species is a breeding pool that holds all the variant forms (or alleles ... The source of this resilience is its genetic diversity. If a new pest or disease strikes a genetically diverse ...

Healthy populations tend to have a large gene pool with many genetic variants circulating. But the path to extinction erodes genetic diversity, because a species’ gene pool shrinks as the ...

Higher genetic diversity also means there’s a greater chance of a species’ survival. Conservation efforts to connect isolated populations — basically expanding the dating pool for a ...

This infusion of genetic diversity could help the animals reproduce more easily and be more resilient to diseases and stressors. “Broadening the gene pool seems like a tremendous opportunity ...

“This suggests that ancient individuals with non-Scandinavian ancestry contributed proportionately less to the current gene pool in Scandinavia than expected based on the patterns observed in ...

The researchers traced how the Scandinavian genome changed over time — and how immigrants to northern Europe influenced the gene pool. The results were published Thursday in the journal Cell.
