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 ...

For years, we’ve been taught that men have one X and one Y chromosome, with the Y carrying the vital gene that initiates male development. But now, scientists are sounding the alarm: the Y chromosome ...

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 ...

For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...

A 3D graphic showing an artist's interpretation of human X and Y chromosomes. On the left are blue bundles of genetic material making an X shape and on the right blue bundles of genetic material ...

Over a century ago, one part of our DNA got labelled the "sex chromosomes." Science and radio journalist Molly Webster explains the consequences... Molly Webster: Is Our Definition Of "Sex Chromosomes ...
