Loss of the Y chromosome in blood cells is common enough that roughly 40 percent of men around age 70 show it, and a review ...

It was once thought that X and Y chromosomes only determine biological sex. However, recent research suggests that X and Y ...

How are these unique sex chromosomes formed? "The sex of a somatic cell as highly differentiated as a neurone may be detected ...

A new study reveals that the loss of the Y chromosome in men’s body tissue could pave the way for cancer to develop in that ...

A new study found that cancer cells selectively chip away gene-rich sections of the Y chromosome, triggering changes that ...

When plants end up with the wrong number of chromosomes, the consequences are usually dire. Cells starved of, or overloaded ...

The near-neutral model of B chromosome evolution predicts that population invasion is quite fast. To test this prediction, in 1994, we introduced males of the grasshopper Eyprepocnemis plorans from a ...

Numerical instability, the gain or loss of whole chromosomes, has received far less attention despite its frequency in ...

A new review published in Science brings together growing evidence that the X and Y chromosomes do more than determine ...
