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 ...

New techniques to detect Y chromosome genes show frequent loss of the Y in tissues of older men. The increase with age is clear: 40% of 60-year-old men show loss of Y, but 57% of 90-year-olds.

Newly generated, complete genomes for the sex chromosomes of six primate species — produced by an international collaboration led by researchers at Penn State and the National Human Genome Research ...

The evolution of sex chromosomes influences reproductive biology and genome evolution across species. In Drosophila pseudoobscura, the Y chromosome has a distinct origin compared to Drosophila ...

Impeccable Cantonese cooking is on show at the Club Rivers restaurant.

Nearly two decades ago, Australian evolutionary biologist Professor Jenny Graves sparked one of the most persistent genetic debates of our time. In a commentary that followed her 2002 research, she ...

New findings challenge researchers' understanding of how the Y chromosome evolved -- rather than being the slowest component of the genome to change, as generally believed, it might just be the ...

Women, on average, live longer than men. This trend can be seen as far back as records stretch, and is true of every country in the world today. Many explanations have been put forward: men take more ...

Researchers 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 produce enough ...
