Two new studies of the evolutionary history of the Y chromosome show that, contrary to popular (if not scientific) belief, the male is not at risk of dying out. The Y chromosome which, among other ...

In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery-how "selfish chromosomes" cheat the rules of genetic inheritance.

When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

Genes do not exist in isolation. Like beads on a string, they sit next to each other on long DNA molecules called chromosomes. So far, little has been known about how the position of a gene on a ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...
