text: Parthenogenesis — the ability to produce offspring from unfertilized eggs — is widespread among invertebrates and now increasingly found in normally sexual vertebrates.
text: Also, even though in birds parthenogenesis is phylogenetically widespread, most of the studies are restricted to galliformes (chickens, turkeys and Chinese painted quail); hence, there is a need for further studies on other avian species in order to establish the evolutionary basis of parthenogenesis in birds.
