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 ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 ...

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

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 ...

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

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 ...

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

It also contains telomerase reverse transcriptase (TERT), which uses TERC to synthesize and add telomeric DNA repeats to the ends of the chromosomes. In contrast to human somatic cells that are ...
