Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males from ...

In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart. This is why it’s taken scientists so long to work out exactly what makes a male a male.

Standard laboratory tests can fail to detect many disease-causing DNA changes. Now, a novel 3D chromosome mapping method can reliably reveal these hidden structural variants and lead to new ...

Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
