A strange discovery in southern Brazil has left the scientific community stunned. In 2021, a female canid was found near ...

Animal hybrids are unusual in nature, though some exist. The mule is a cross between a female horse and a male donkey, while a liger is created by crossing a female tiger and a male lion, for example.

But, this phenomenon, known as hybrid sterility, isn't limited to the animal kingdom: Plenty of plants produce viable hybrids that are genetic dead-ends as well.

The surprising degree of evolutionary flexibility in this meiotic surveillance system may contribute to the observed variation in patterns of hybrid sterility and in rates of polyploidization.

On the other hand, the data suggest that the regulation of hybrid sterility is not binary, meaning there are not either completely fertile or completely sterile animals in the wild, but a rather ...

The animal kingdom showcases surprising hybrids, offspring of different species sharing traits. These real-life creatures, some natural and others captive-bred, challenge biology. Mules, ligers, and ...

But, this phenomenon, known as hybrid sterility, isn't limited to the animal kingdom: Plenty of plants produce viable hybrids that are genetic dead-ends as well.

The genomes of both plants and animals seem to act as engines for speciation, as they are 'hard-wired' to encourage the development of new species, according to findings on two very different ...

Apparently, grizzlies were moving north into polar bear territory. Since then, several hybrid animals have appeared in and around the Arctic, including narwhal-beluga whales and mixed porpoises.

The hybridization of animal species is often portrayed as rare and strange, or else the result of human-forced matings, as is the case with ligers (lion-tiger hybrids) and mules (horse-ass hybrids).

But, this phenomenon, known as hybrid sterility, isn't limited to the animal kingdom: Plenty of plants produce viable hybrids that are genetic dead-ends as well.
