The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

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 ...

Today, the extreme male brain (EMB) theory is the main rival to the imprinted brain theory—at least where explaining autism is concerned. A new study has looked for direct evidence of the effects of ...

The biological necessity of the Y chromosome is undergoing a fundamental reassessment as evidence confirms its disappearance in specific mammalian lineages. While this chromosome has served as the ...

The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world including ...

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 ...

In mice, female germ cells can develop into viable ova in male testes, Japanese researchers report this week. Their paper in PNAS suggests that sex determination occurs early in embryonic development ...
