Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging. When you purchase through links on our site, we ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Researchers at Linköping University in Sweden made an unexpected discovery while investigating genetically unique women. Their insights advance our understanding of our most enigmatic chromosome, the ...

A gene on the X chromosome revs up inflammation in the female brain, which may explain why rates of multiple sclerosis are higher in women than in men, scientists suggest. When you purchase through ...

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 ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

I married a tall woman out of love, partly from genetic ambition. I figured we’d gift our kids a vertical advantage. It turns out that Mother Nature and Friar Mendel’s peas don’t translate into ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Now, ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...
