Researchers identified an unusual genetic mutation in orange domestic cats that has not been found in any other animal, according to a new study.

This mutation is sex-linked, explaining the higher prevalence of orange coats in male cats. The effect appears limited to pigmentation, with no evidence of broader physiological or behavioral impact.

Approximately 80% of orange cats are males, including the four orange cats owned by the Short Wave team. Scientists have long suspected that orange color was a sex-linked trait — hiding ...

The Israeli Health Ministry’s “basket” of covered services, medications and tests now includes the uniform genetic testing that reveals this mutation. The test is available free of charge.

The sperm of a man carrying a rare genetic mutation linked to cancer was used to conceive scores of children across Europe, prompting calls for greater regulation and a limit on the number of ...

An H5N1 bird flu mutation associated with increased infectiousness and disease severity has been found in two cats. Since the beginning of this year, more than 50 cats have been infected with H5N1 ...

Scientists from the Scripps Research Institute are reporting that it would take just a single mutation in the version of bird flu that has swept through U.S. dairy herds to produce a virus adept ...
