So 23 of your 46 chromosomes come from a parent egg cell, and the other 23 come from a parent sperm cell. Scientists number the first 22 of these pairs 1 through 22. These are known as autosomal ...
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 ...
Meiosis II resembles a mitotic division, except that the chromosome number has been reduced by half. Thus, the products of meiosis II are four haploid cells that contain a single copy of each ...
The X chromosome is not only bigger than the Y but also houses a significantly larger number of genes responsible for protein ...
The octopus just revealed another one of its secrets: what determines its sex. University of Oregon researchers have ...
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’t ...
Researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on ...
