Orange cats, those adorable, often mischievous felines, have long puzzled scientists. Known for their vibrant color, they ...

X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active (blue). A ...

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed – so the other is randomly inactivated. Some cells use only a ...

Researchers from the University of California, San Francisco (UCSF) say they have now found that when the brain cells of female mice express only a maternal X chromosome, the animals’ memory and ...

Brain cells, or oligodendrocytes (green), in the hippocampus are marked with the GFP genetic marker in the mouse brain. These cells often deteriorate during aging. Image credit: Gadek et al., Science ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...

A new study provides new insight into height differences between adult men and women, demonstrating that Y chromosome genes contribute more to height than their X chromosome counterparts. A Geisinger ...
