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 ...

Once upon a time, the Y chromosome — responsible for determining male sex — was as robust as its X counterpart. Fast forward a few million years, and it’s now a slimmed-down version of its ...

A recent study has hinted at a possible connection between the X chromosome inherited from mothers and accelerated brain ...

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

How do scientists find their way around a chromosome? With chromosome maps called idiograms, researchers can pinpoint the locations of genes and locate abnormal gene forms. Aa Aa Aa Most ...

The extinction of the Y chromosome may result in new species of humans. That isn’t the plot for a dystopian sci-fi film, but genuine scientific theory. We were all taught that the X and Y genes ...

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

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

With the publication of Ohno's watershed monograph 1, molecular genetic characterization of the mammalian sex chromosomes has radically altered our view of X-chromosome inactivation and the ...

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed – so the other is randomly inactivated. Some cells use only a ...

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