The study's goals included generating data that could be used to address concerns about inbreeding and genetic diversity within the breed, while also offering breeders valuable insights to guide ...

Feral dogs living near Chernobyl differ genetically from their ancestors who survived the 1986 nuclear plant disaster—but these variations do not appear to stem from radioactivity-induced mutations.

On April 26, 1986, the worst nuclear disaster since World War II decimated Chernobyl in the Soviet Union. Nearly 40 years later, a lot has changed. Chernobyl, for one, is now within the borders of ...

Roughly 10,000 years ago, a small group of woolly mammoths found themselves stuck on an island off the coast of Siberia. While their mainland peers disappeared, this isolated herd multiplied.

A new genomic analysis deepens the mystery. The study offers the fullest account to date of the inbreeding, deleterious mutations and low genetic diversity experienced by this population during ...

Because inbreeding can negatively impact survival ... vegetation and the pollinators and birds that live there. ... Single Mutation in H5N1 Influenza Surface Protein Could Enable Easier Human ...

Such topics include: the rate of appearance of new, harmful mutations; the effect of continued inbreeding on fitness; differences in rates of evolution between genes transmitted maternally vs.

Some experts theorized that this could be radiation-induced mutations at work, but others disagreed, saying how isolating the cause other selective pressures or inbreeding can be difficult.
