The offspring produced by apomictic parthenogenesis are full clones of their mother, as in aphids. [23] Parthenogenesis involving meiosis is more complicated. In some cases, the offspring are haploid (e.g., male ants). In other cases, collectively called automictic parthenogenesis, the ploidy is restored to diploidy by various means. This is ...
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

There are many animals that can give birth by parthenogenesis, according to National Geographic. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish ...
The lizards reproduce by parthenogenesis and are clones of their mother. Under normal reproductive processes, a species has each chromosome pair separated, copied, and paired back with its counterpart. The desert grassland whiptail lizard, however, has chromosome triplets where each triplet is paired with its copy rather than its counterparts ...
A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.” It tends to occur in ...
In 2023, a second clone of the original stallion, named Ollie, was born; this marked the first instance of multiple living clones of a single individual of an endangered species being alive at the same time. [128] Also in 2020, a clone named Elizabeth Ann was produced of a female black-footed ferret that had no living descendants. [129]
It was concluded after DNA testing that the reproduction was parthenogenetic, as the female pup's DNA matched only one female who lived in the tank, and no male DNA was present in the pup. The pup was not a twin or clone of her mother, but rather, contained only half of her mother's DNA ("automictic parthenogenesis"). This type of reproduction ...
If you were old enough to watch the news or read the paper back in the late 1990s, you very likely remember Dolly, the cloned sheep. Born in 1996, the researchers responsible for cloning her kept ...
