Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact ...

A study conducted by a research team at the Crick Institute identified important genes on the Y chromosome that regulate ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair.

plays a critical role in the disintegration of the Y chromosome, linking LOY to genomic instability and aging processes. LOY in human male cells was first identified over 60 years ago but gained ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don’t ...

Researchers say study represents a resource that could also help to dissect Y-gene functions in other tissues.

The disappearance of the Y chromosome could result in the evolution of a new sex-determining gene or other reproductive mechanisms, with significant implications for human reproduction.

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is ...

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