It's a regrettable reality that there is never time to cover all the interesting scientific stories we come across each month ...

Your orange cat may host a never-before-seen genetic pathway for color pigmentation, according to new studies ...

There are more male orange cats than females because this gene is located on the X-chromosome, which males only have one copy ...

The existence of orange cats dates back to at least the 12th century, but scientists have only had theories that a sex-linked ...

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

Stanford Medicine researchers discover mechanisms of sex-linked genetic mutation giving rise to ginger felines.

The mutation deletes a section of the cat's DNA, and increases the activity of a gene in X chromosomes — thread-like structures of DNA that carry hereditary information passed on from parent to ...

“For more than a century, orange coat color in cats has been recognized as an exception to the genetic rules that explain ...

World Boxing says Algerian boxer Imane Khelif, who won gold at Paris Olympics, won't be allowed to compete until she undergoes sex testing.

In female cats (and all female mammals), one of the two X chromosomes in each cell is randomly switched off in a process known as X chromosome inactivation, so even if the mutation is present, it is ...

Females are more likely to be tortoiseshell or calico because they have two X chromosomes, and therefore have more genetic coat color options to ‘choose’ from. The location of the mutation on ...
