The Y chromosome is the smallest chromosome, and holds the least amount of genes, but scientists are still learning about all of its biological functions. Research has shown that many men start to ...

Researchers from Tokyo Metropolitan University have identified unifying features in the early evolution of X and Y chromosomes. Newly evolved sex chromosomes in three fruit fly species showed the same ...

For decades, the Y chromosome—one of the two human sex chromosomes—has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

What was once the final frontier of the human genome — the Y chromosome — has just been mapped out in its entirety. Led by the National Human Genome Research Institute (NHGRI), a team of researchers ...

In the 1960s, doctors counting the number of chromosomes in human white blood cells noticed a strange phenomenon. Frequently—and more frequently with age—the cells would be missing the Y chromosome.

Chromosomes change over time, whether through the process of aging or exposure to harmful substances in the environment. Steven Puetzer/The Image Bank The Y chromosome can be lost through the process ...

Did you know that your baby’s genetic makeup was determined at conception? From the moment the sperm met the egg, your little one’s genetic code — DNA — began forming. It’s made up of 23 pairs of ...
