Stingray's Mysterious Pregnancy Sparks Scientific Debate

A female stingray at a North Carolina aquarium has become pregnant without a male mate, leading experts to speculate on a rare case of parthenogenesis.

Charlotte, a round stingray, has not encountered a male mate in at least eight years but is due to give birth to up to four pups.
Experts dismiss the theory of interspecies impregnation with sharks, citing incompatible anatomies and DNA.
Parthenogenesis, a form of asexual reproduction, is considered the most plausible explanation for Charlotte's pregnancy.
This could be the first documented case of parthenogenesis in the round stingray species.
Charlotte is expected to give birth within the next two weeks, with plans to move her to a larger tank for the offspring.
