“A litter produced by sexual reproduction is usually much larger than one produced via parthenogenesis if it’s an animal that gives birth to litters,” Chapman said. “And you will often see ...

Depending on the species, this trigger may come from changes in an animal’s or insect’s body or its environment. The terms for eggs produced by parthenogenesis are: The sex of the eggs depends ...

“They could simply say that it’s very likely that dinosaur DNA carried the gene variant that allows for parthenogenesis.” With the discovery limited to one captive animal, many questions remain.

Some female birds, reptiles and other animals can ... have only noticed parthenogenesis when solo females had young or when researchers were monitoring a population’s genes.

Virgin births' have been widely documented in animals like snakes and bees. However, this is the first evidence of parthenogenesis in a crocodile. It's not clear why some animals make the switch ...

“I think in any other animal ... from a male. When parthenogenesis occurs, the offspring are always female. And while their genes are similar to their mother’s, they are not exact clones.

Asexual reproduction is common for animals like starfish, deep-sea worms, and stick insects, but among vertebrates, it's a rarity. A process called parthenogenesis allows some female animals to ...

Feldheim said he’s counted 15 species of elasmobranchs where parthenogenesis has been observed by scientists since then. The phenomenon has been observed in every class of animals, except for ...

which makes animals born this way easier to identify, has shown that they are not all that rare. “It’s much more widespread than people think,” he said. It’s possible that parthenogenesis ...
