The Y chromosome, which determines the sex of human and other mammal babies, is slowly degenerating and may disappear within a few million years, raising fears of extinction. However, a 2022 study ...

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.

However, the large chunk that has been sequenced contains versions of several of the same genes that are found in the modern human Y chromosome. In modern humans, a Y chromosome gene called SRY ...

A tangible timekeeper of history, the Y chromosome allows us to trace human evolution, track migration patterns and relatedness in groups of people, and answer paternity questions going back ...

It’s not clear why these backups have evolved. The new Y chromosome sequences could spell change for metagenomics research, which involves sequencing microbial genomes. Human DNA contaminants often ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of ...

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 ...

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 ...

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