A new analysis of ancient DNA has found that Neanderthal genomes contain 62 percent more ancestry from anatomically modern ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Researchers from Tokyo Metropolitan University have taken a big step in solving the mystery around why animals evolve sex chromosomes. It had long been proposed that sex chromosomes evolved to reduce ...

Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene ...

A nearly gapless genome sequence of the echidna, an egg-laying mammal with multiple sex chromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual sex ...

Forget the battle between the sexes. There’s a tinier battle raging within the sexes — at the genetic level. In some species’ sperm, X and Y chromosomes wrestle for dominance, each trying to improve ...

Here’s a quick reality check: ice cream sales go up in summer, and so do drownings. But no one thinks Ben & Jerry's is a silent killer. It’s correlation, not causation. Yet this same logical ...

WASHINGTON, Aug 23 (Reuters) - Scientists have taken an important step forward in understanding the human genome - our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in ...
