A genetically male strain of giant kelp can produce eggs

Researchers from the Max Planck Institute for Developmental Biology in Tübingen and their collaborators describe a strain of giant kelp that is genetically male, but presents phenotypic features of females. Their findings ...

Grape genetics research reveals what makes the perfect flower

Wines and table grapes exist thanks to a genetic exchange so rare that it's only happened twice in nature in the last 6 million years. And since the domestication of the grapevine 8,000 years ago, breeding has continued to ...

Snake sex chromosomes say less about sex and more about survival
