A new study published in Nature Genetics by the Lymphoid Development Group at the MRC Laboratory of Medical Sciences has reveals that the contribution of cells expressing maternal or paternal X ...

The ape sex chromosomes have now been fully sequenced. Rapid evolution has led to extreme differences in the Y chromosome between species, whereas the X chromosome experienced much less dynamic ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share upwards ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
