What stands out the most about this ancient cephalopod sex chromosome is how little the chromosome has changed over time.

Study reveals the impact of X chromosome on brain aging in women. Learn how maternal and paternal X chromosome can influence ...

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 ...

Cephalopods may have the oldest sex chromosomes of any animal, according to a new discovery in the octopus genome. That's a ...

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 ...

University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has ...

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 ...

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 only ...
