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.

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...
