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 ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. In a new study, scientists probed the ways in which the X chromosome may change with age and ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

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 ...

The human Y chromosome, responsible for male sex determination, has forfeited 97% of its ancestral genes over the past 300 ...

Scientists remain divided over whether the human Y chromosome will eventually vanish. But clinicians say the real concern ...

University of Virginia School of Medicine researchers have discovered a gene on the Y chromosome that contributes to the greater incidence of heart failure in men. Y chromosome loss in men occurs ...

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 ...

The lab of developmental biologist Dr. Eric Lai has been studying evolutionary battles of the sexes in fruit flies. This colorful snapshot, courtesy of the Lai Lab, depicts sperm maturation in fruit ...
