Researchers are gaining a new appreciation for the genes on the X and Y chromosomes and how they shape sex differences in ...

New research shows the X chromosome influences disease risk, immunity and drug response beyond its role in sex.

Unique sex chromosomes occur in species from humans to birds, worms, and flies. An unequal pair of sex chromosomes, each carrying a different complement of genes, requires specific efforts to regulate ...

Researchers at the University of California San Diego (UCSD) have demonstrated an intriguing new variation on the CRISPR gene-editing system, which involves fixing a mutation on one chromosome by ...

Researchers at University College Dublin have identified a genetic "switch" that determines the sex of cannabis plants, and ...

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 ...

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 ...

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 ...
