Two new studies of the evolutionary history of the Y chromosome show that, contrary to popular (if not scientific) belief, the male is not at risk of dying out. The Y chromosome which, among other ...

Eighty percent of patients with autoimmune diseases are female. These diseases are one of the top 10 leading causes of death for women under 65, and cases are increasing annually worldwide. There is ...

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 ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...
