Study in mice and human cadavers hints that a brain-protective gene in the chromosome becomes more active with age.

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 ...

“In typical aging, women have a brain that looks younger, with fewer cognitive deficits compared to men,” said Dr. Dena Dubal ...

Successful meiosis requires the silencing of both the X and Y chromosomes during a particular window of time. Genes on the Y chromosome regulate this process and could only be heritably transposed to ...

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 recent Trump executive order defines sex based on gamete size. But the order oversimplifies genetics, hormones and reproductive biology.

he said. Phillippy and his colleagues found 110 new genes, 41 of which are predicted to code for proteins. The majority were extra copies of the TSPY gene, which is involved in sperm production. It’s ...

Small sections of the chromosome, called genes, code for the RNA and protein ... The sex chromosomes in humans are called X and Y. Females carry two X chromosomes, while males carry one X and ...

DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of antibiotic resistance. Cornell University researchers have discovered a new ...
