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. The X chromosome passed from mom to ...

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 ...

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 ...

Biotechnology company, Amgen, has announced that it has entered into a definitive agreement to acquire deCODE Genetics, a global leader in human genetics, for US $415 million. The all-cash ...

With so many at-home DNA tests now available, learning more about your genetics and ancestry is easier than ever. All you have to do is choose an online service, receive a DNA testing kit ...

The battle against brain aging has a surprising new player: the X chromosome we inherit from our mothers. Recent research reveals that this genetic hand-me-down could influence how quickly our brains ...

A structural abnormality can include an alteration to the structure of the chromosome, as the name suggests. However, a numerical abnormality means that an individual is either missing one of the ...
