Researchers at the University of California San Diego (UCSD) have demonstrated an intriguing new variation on the CRISPR gene-editing system, which involves fixing a mutation on one chromosome by ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

Chris Kaelin, a geneticist at Stanford Medicine, recently solved the riddle of why so many orange cats are male. In a groundbreaking study, Kaelin and his team discovered a unique mutation that ...

The existence of orange cats dates back to at least the 12th century, but scientists have only had theories that a sex-linked genetic mutation is behind it. Now, new research has pinpointed the exact ...

The 23 rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

A woman had cancer 5 times before she turned 36, the first time when she was two. A study found she has never-before-seen mutations that were thought to be impossible to survive. It shows the ...

An international study has identified more than 50 genes on the X chromosome in which mutations may cause poor sperm production. Nearly half of all men with low or zero sperm count have no medical ...
