Modern genetics reveals that over 50 genes across many chromosomes—not just X and Y—govern sex development. The term “sex ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

A biology professor who was fired from a Texas community college for teaching students that X and Y chromosomes determine sex has been reinstated. First Liberty Institute, a law firm that defends ...

Newly generated, complete genomes for the sex chromosomes of six primate species — produced by an international collaboration led by researchers at Penn State and the National Human Genome Research ...

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

That changed in 2014, when Swedish scientists showed that Y loss in blood cells correlates with how long men live – those who have Y loss in some of their cells die five years sooner. Many further ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...

Women age differently from men when it comes to health—particularly in conditions like cardiovascular disease and neurodegenerative disorders such as dementia and Parkinson's. A team at the Technical ...
