The final pair are sex chromosomes, which scientists label X and Y. The Y chromosome is associated with the development of male sex characteristics.

The Y chromosome was once used to label people as criminal. A new complete Y chromosome sequence just might combat this dangerous myth. By Christopher R. Donohue & Anna Rogers.

The work reveals a complete catalog of the genes in the male sex chromosome — the last human chromosome to be fully sequenced — and how they're organized.. The findings, published Wednesday ...

Understanding how the extra X chromosome contributes to longevity and cognitive health could potentially lead to therapeutic approaches that mimic these protective effects in both men and women.

The Y chromosome has seen significant changes over the course of human evolution. "In comparison to the X, the Y is tiny. There are only 45 genes on the Y chromosome, ...

Scientists fully sequence the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other issues.

For decades, researchers dismissed the Y chromosome as a “genetic wasteland,” a graveyard where genes (and careers) go to die. advertisement That has to do, in part, with the Y chromosome’s ...

Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males ...

The Y chromosome, along with the X chromosome, is often discussed for its role in sexual development. While these chromosomes play a central role, the factors involved in human sexual development are ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share ...

In many organisms, X and Y chromosomes can jettison extra material during DNA-swapping sessions with each other. But the campion lost much of its ability to tidy up large parts of its sex ...
