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 ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that the Y has little biological importance beyond sex determination.

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 ...

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 ...

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 ...

This loss, evident in almost half of older men, is associated with serious diseases throughout the body and a shorter ...
