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 ...

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 ...

Sex, Genes and Chromosomes: Their Discovery, Function and Evolution Jennifer A. Marshall Graves Cambridge Univ. Press (2026) “Sex is the most profound normal difference between human individuals,” ...

The sex chromosomes X and Y are non-homologous, meaning they do not share many gene sequences or structures, but both contain a gene called SHOX located in pseudoautosomal region 1 (PAR1), a small ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes. Women ...

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 ...

Cholesterol-lowering statins are among the most widely prescribed drugs in the world. They can have side effects, however, including muscle pain that affects twice as many women as men. When Karen ...
