The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we've seen it shrink at an alarming ...

The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes and is full of junk DNA ...

The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we ...

Scientists historically have argued that evolution proceeds through gradual development of traits. But how can incremental changes apply to the binary switch between two sexes, male or female? Researchers at Case Western ...

New research has identified the key to becoming male is an enzyme that "unravels" DNA to trigger male development of the embryo, a discovery that may give greater insight into intersex disorders.
