Before species go extinct, their populations often shrink and become isolated. Healthy populations tend to have a large gene ...

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 ...

The target for dairy producers to maintain inbreeding at less than 6.25% has been called into question following the extensive analysis of data both internationally and in the UK. The target was set ...

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.

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 ...

Blood does more than just carry oxygen and nutrients. Its many “markers,” known as antigens, can trigger unexpected responses. Most folks have heard about the blood groups A, B, and O, and the Rh ...

Similipal Tiger Reserve in Odisha is home to the world's only population of melanistic tigers, a rare genetic variant of the Royal Bengal Tiger. Melanistic tigers, with their distinct coat pattern ...

For 30 years, researchers have known that Huntington's is caused by an inherited mutation in the Huntingtin (HTT) gene, but they didn't know how the mutation causes brain cell death. A study ...

One of the earliest strains of bird flu isolated from a human in Texas shows a unique constellation of mutations that enable it to more easily replicate in human cells and cause more severe ...

Video: Broad Institute of MIT and Harvard At a glance: Study explains long-standing question of why Huntington’s disease symptoms typically do not appear until midlife even though patients are born ...

This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer. While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms ...
