Scientists induce 'virgin birth' in fruit flies by manipulating genes for the first time

Scientists discovered genetic cause for parthenogenesis in fruit flies and induced the ability in another species.
Parthenogenesis allows females to reproduce without mating and occurs naturally in some insects and isolated animals.
Researchers identified and altered genes responsible for 'virgin birth' ability in fruit flies.
Findings confirm genetic basis of facultative parthenogenesis and provide starting point to study evolution.
Induced parthenogenesis in agricultural pests could have implications for pest control and food security.
