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 evolve to reduce ...

WASHINGTON (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 males, an ...

Sex chromosomes generally evolve from a homomorphic to heteromorphic state. Once a heteromorphic system is established, the sex chromosome system may remain stable for an extended period. Here, we ...

European cuckoos lay very different eggs depending on the host species. Genetic analyses have revealed how this adaptation is inherited without leading to speciation.

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 ...

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 ...
