Scientists have nailed the biomechanics of a centuries-long puzzle on how freshwater flatworms known as planarians reproduce. The asexual freshwater worms, notoriously difficult to study, tear ...

The Pro1 protein helps express mating-related genes in different species of fungi. But what happens when Pro1 malfunctions? Researchers from the Tokyo University of Science have found that mutations ...

A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those ...

Reproduction in the animal kingdom has historically been sexual. Cloning the sheep Dolly in 1997 moved us closer to the possibility of duplicating other animals or humans asexually, but the practice ...

Biology textbooks maintain that the main function of sex is to promote genetic diversity. But in a new article, two researchers say that's not the case. They propose that although diversity may result ...

The ‘paradox of sex’ refers to the puzzle of why the sexual mode of reproduction is more common among living beings than the asexual mode. Sexual reproduction requires at least two mates, exposes ...
