With seven different sexes to choose from, the single-celled organism Tetrahymena thermophila determines its biological mating type in a game of molecular chance, new research finds. Tetrahymena are ...

The rad52-1 mutation prevents homothallic mating type interconversion and reduces mitotic recombination in yeast. It has been previously reported that rad52-1 abolishes meiotic recombination. These ...

The mating process is one of the most important mechanisms for maintaining genetic variation in natural populations. The emergence of sexual reproduction turned out to be the most important ...

It's been more than 50 years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or ...

Conjugation (or mating) of ciliates is a unique phenomenon among living beings. They have sex not for reproduction or pleasure — they seek to increase genetic variation. Scientists from St Petersburg ...

Fungal mating systems represent a fascinating arena of biological complexity that underpins the remarkable genetic diversity seen in these organisms. Unlike animals, fungi do not have distinct sexes ...

Recognition systems have evolved to ensure that a plant mates only with a genetically different plant and not with itself, hence preventing inbreeding. Recognition systems can be found in at least 100 ...

Some species have the equivalent of many more than two sexes, but most do not. A new model suggests the reason depends on how often they mate. We tend to think about two biological sexes: male and ...

Biologists have known for decades that there are up to seven sexes of the single-celled organism known as Tetrahymena thermophila — but they didn't know exactly how those different sexes "did it." ...

From Quanta Magazine (find original story here). We tend to think about two biological sexes: male and female. But before the evolution of eggs and sperm—before sex cells began to diverge in size and ...
