While humans often struggle to find a partner who is both physically attractive and a reliable co-parent, yeast may already have cracked the formula for the perfect match. When choosing mates, these ...

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

A two-decade study on serially cloned mice revealed that repeated cloning causes grave genetic mutations to accumulate, eventually leading to fatal consequences. The research challenges the notion of ...

A large-scale genetic analysis of East Asian individuals led by Fuu-Jen Tsai of the China Medical University Hospital, finds ...

Human embryo screening undermines parental trust, stigmatizes disability, narrows genetic diversity, and erodes the foundation of unconditional love. Artificial intelligence compounds these dangers by ...

Genetic diversity is essential to the survival of a species. It’s easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, ...

TOKYO -- Sexual reproduction is essential for mammals to eliminate harmful genetic mutations that build up through cloning, a ...

When roundworms stop reproducing, they can still move and function normally but lose their ability to detect certain food odors that once led them to their meals. Researchers at Nagoya University have ...

As the generations dragged on past the 27th iteration, the birth rate began to silently collapse. By the 57th generation, a mere 0.6 percent of the cloned embryos survived. The 58th generation ...
