Deep within the cells of mice, a genetic arms race is unfolding between X and Y chromosome genes, battling for dominance in ...

In evolutionary terms, fitness is defined as an organism's ability to survive and reproduce its genes into the next ...

The research reveals that this sex-based difference can be traced to a gene on the Y chromosome. The discovery, published in Science Advances, not only showcases the critical need to understand ...

While this internal rivalry is usually hard to see, it becomes clearer when it involves genes on the X and Y chromosomes, ...

In evolutionary terms, fitness is defined as an organism's ability to survive and reproduce its genes into the next ...

The sex-ratio balance is maintained as genes on the X and Y chromosomes co-adapt to keep each other in check. How this happens has been a mystery, as sperm cannot be grown in a lab. The U-M team found ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Females have two X chromosomes (XX). Males have one X and one Y chromosome (XY). All eggs contain one X chromosome. Half of sperm contain one X chromosome and half contain one Y chromosome.
