How diseases develop and how the body ages can differ between females and males, but the biological reasons for these ...

Scientists discovered a new gene family on the Y chromosome of deer mice, challenging the belief that the chromosome only ...

Cells that acquire a doubled genome after a failed division step survive and proliferate far more effectively than cells left ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

Damage to DNA in cancer cells can lead to pieces breaking off chromosomes and floating away, like icebergs cracking off from ...

Scientists in Japan have developed a rat-mouse hybrid embryo from a single frozen rat chromosome transplanted into a mouse ...

Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...

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 ...

The 2010 discovery that early humans and Neanderthals once encountered one another and had babies was a scientific bombshell that electrified the field of human origins. Now, geneticists at the ...
