Researchers 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 produce enough ...

New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive ...

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X ...

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

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X ...

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 ...

A study finds that female mice using only a maternal X chromosome experience faster brain aging, leading to memory loss.

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

The X chromosome carries at least 150 genes linked to intelligence. Since the mother has two X chromosomes to pass along while the father only has one, the mother’s contribution to the child’s ...

Scientists have completed construction of the final chromosome in the worlds' first synthetic yeast genome following more than a decade of work, opening new possibilities for creating resilient, ...
