Induced parthenogenesis of this type in mice and monkeys results in abnormal development. This is because mammals have imprinted genetic regions, where either the maternal or the paternal chromosome is inactivated in the offspring for development to proceed normally.
In 2004, scientists at Tokyo University of Agriculture used parthenogenesis to create a fatherless mouse. Using gene targeting, they were able to manipulate two imprinted loci H19/IGF2 and DLK1/MEG3 to produce bi-maternal mice at high frequency [68] and subsequently show that fatherless mice have enhanced longevity.

In mice, natural mating involves fertilization of an egg by a sperm.Kaguya was created in laboratory from two egg cells. Kaguya was the first bimaternal mouse created in laboratory using two eggs from female parents by Tomohiro Kono and colleagues at Tokyo University of Agriculture. [1]
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 ...
Researchers were able to pinpoint the genes that control fruit fly parthenogenesis — the scientific term for virgin birth in animals. Scientists take major step in unraveling mystery of virgin ...
[20] [21] [22] Nevertheless, in 2018 genome editing allowed for bipaternal and viable bimaternal [23] [24] mouse and even (in 2022) parthenogenesis, still this is far from full reimprinting. [25] Finally in March 2023 viable bipaternal embryos were created. [26] No naturally occurring cases of parthenogenesis exist in mammals because of ...
First artificial parthenogenesis in mammals: (2022) Viable mice offspring was born from unfertilized eggs via targeted DNA methylation editing of seven imprinting control regions. [ 84 ] Human cloning
Parthenogenesis occurs in the wild in many invertebrates (e.g. water fleas, rotifers, aphids, stick insects, some ants, bees and parasitic wasps) and vertebrates (mostly reptiles, amphibians, and fish). It has also been documented in domestic birds and in genetically altered lab mice.
