‘Virgin birth’ genetically engineered into female animals for the first time
Scientists have successfully genetically engineered female fruit flies to reproduce without a male, marking the first instance of "virgin birth" in an animal. The offspring of these flies were also able to reproduce without mating.
The researchers identified 44 genes potentially involved in parthenogenesis by comparing gene activity in sexually reproducing flies with that in parthenogenetic flies. By altering combinations of these genes in fruit flies, they induced parthenogenesis in roughly 11% of female flies.
“In our genetically modified flies, the females waited half their lives - about 40 days - to find a male,” explained the researcher from the University of Cambridge.
