With such an unstable composition, the Y chromosome is at risk of disappearing over multiple generations. Males tend to only have one copy of the Y chromosome, ...

A nearly gapless genome sequence of the echidna, an egg-laying mammal with multiple sex chromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual sex ...

Despite its macho connotations, the Y chromosome is among the tiniest of the 46 chromosomes in the human genome. It makes up only 2 percent of a human cell’s total DNA. But because of its ...

Loss of the Y chromosome (LOY) in men, a dynamic mutation linked to aging, impairs immune function and increases risks of cancer, Alzheimer’s, and cardiovascular diseases, making it a promising ...

A not-so-silent X leads to a brain-restoring factor. One of the 22 genes that had 'escaped' silencing on the X chromosome, PLP1, stood out to the researchers.

Approximately 80% of orange cats are males, including the four orange cats owned by the Short Wave team. Scientists have long suspected that orange color was a sex-linked trait — hiding ...
