A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery—how "selfish chromosomes" cheat the rules of genetic inheritance. The researchers found that ...

When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

Mitochondria in plants can be inherited from the father more often than expected. The findings come from Wageningen ...

Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics because at the molecular level, we have a lot in common with these organisms. Scientists used a ...

While whiskey, real estate portfolios and emotional intelligence tend to improve with age, sperm does not. New research suggests that your spunk does indeed sour with time — at least in terms of how ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

An egg cell and a sperm need to hold together tightly in the Fallopian tube in order to fuse, resulting in the creation of a new organism. One key part of this process involves the proteins Juno, on ...

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm production, new research has revealed. In a landmark study published today ...

New research shows it's possible to reprogram skin cells into eggs that can be fertilized in the lab, though it's just a proof of concept for now. Reading time 3 minutes A team of scientists has ...
