Researchers confirmed that sperm accumulate mutations over the years, increasing the risk of transmitting diseases to ...

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

A Nature study shows sperm from older fathers carry more disease-linked mutations, revealing how age and cell competition ...

As a group, carriers of recessive disorders are slightly less healthy and have a reduced chance of having offspring. This disadvantage is greatest for carriers of a recessive gene for intellectual ...

Research reveals that as men age, their sperm accumulates mutations, increasing the risk of passing genetic disorders to ...

Sexual selection can promote adaptation if sexually selected traits are reliable indicators of genetic quality. Moreover, models of good genes sexual selection suggest that, by operating more strongly ...

In the estimated 5 million years since humans and chimpanzees began diverging, they've acquired major anatomical and cognitive differences. Nevertheless, some of the strongest evidence for positive ...

The use of genetic testing and selection of embryos derived from in vitro fertilization (IVF) has long sparked public debate, ...

Scientists built a complete wheat gene map showing how different genes control plant growth and stress response.
