Asexual conundrums. Parthenogenetic species are rare but found among a variety of life, including reptiles, amphibians, ...

Green anacondas are on a lengthening list of animals able to give birth without a mate. The more animals in which biologists discover asexual reproduction, the more they are rethinking the basics ...

Parthenogenesis, a form of asexual reproduction where embryos develop from unfertilized eggs, has been observed in captive female animals that are separated from males for extended periods of time.

Parthenogenesis, a form of asexual reproduction in which an egg develops in the absence of fertilisation, has traditionally been associated with invertebrates. However, recent discoveries have ...

"First, you should know that parthenogenesis is asexual reproduction of an organism in which a female produces an embryo without a male present to fertilize the egg," wrote Dr. April Smith ...

Asexual conundrums Parthenogenetic species are rare but found among a variety of life, including reptiles, amphibians, nematodes, fish, and birds. Their chances of long-term existence are slim.

Scientists are studying whether a phenomenon called parthenogenesis, a rare form of asexual reproduction, or delayed fertilization, where fertilization occurs long after mating, could have occurred.

Because it’s challenging to track how often parthenogenesis happens in the wild, many “firsts” in asexual reproduction are seen in animals in human care, a National Geographic article reported.

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 or ...

Her logic goes like this: For most animals, sexual reproduction is a better option than parthenogenesis. It gives their babies more diverse genes, and that makes them stronger.

For the first time, scientists have induced facultative parthenogenesis, a form of asexual reproduction, in an animal that usually reproduces sexually. An estimated 76 percent of fruit flies can ...
