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 ...

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 ...

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

With a few exceptions, eukaryotic chromosomes have a single centromere that ensures their accurate segregation during mitosis. Chromosomes that lack centromeres segregate randomly during mitosis ...

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

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 ...

Females (XX) carry twice as many X-linked genes on their sex chromosomes as males (XY). How do cells control gene expression to manage this potentially lethal dosage problem? A prime example of X ...

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 ...

New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and paternal X chromosomes.

If this hereditary tradition has been closely followed, the Y chromosomes of the Cohanim today should bear some resemblance to one another because of their unbroken link back to a common ancestor ...
