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 chromosomes ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...

Researchers found that Neanderthals carried excess modern human DNA on their X chromosomes, pointing to predominantly male ...

Interbreeding Direction Solves Neanderthal X Chromosome Mystery Homo sapiens females unions with Neanderthal males explain X chromosome DNA gap ...

Newly generated, complete genomes for the sex chromosomes of six primate species may inform conservation of these endangered species and shed light on sex-related genetic diseases in both humans and ...

Sex is determined in a variety of different ways throughout the animal kingdom. In mammals, it is determined genetically, not by temperature, as it can be in reptiles. Typically, females have two X ...

A new Neanderthal DNA study suggests interbreeding between modern humans and Neanderthals favored pairings of female humans with male Neanderthals. This finding challenges traditional evolutionary ...
