Researchers have uncovered the mechanism behind the arms race for mouse X and Y bearing sperm to fertilize an egg.

While this internal rivalry is usually hard to see, it becomes clearer when it involves genes on the X and Y chromosomes, which determine the sex of mammals. A hidden battle between X and Y chromosome ...

A study from University of Michigan researchers has uncovered the mechanism behind the arms race for mouse X and Y bearing sperm to fertilize an egg, analogous to space races to reach the moon.

A study published in Proceedings of the National Academy of Sciences by the University of Michigan researchers has uncovered the mechanism behind the arms race for mouse X and Y bearing sperm to ...

The mammalian X chromosome has many genes that the Y does not—a feature that has special implications for sperm, and also for scientists. The mouse X chromosome carries two protein receptors that when ...
