Known by scientists as 'parthenogenesis', this natural form of asexual reproduction lets healthy offspring develop from a female's unfertilised eggs. Only last month, a female lizard at a zoo near Birmingham gave birth to eight hatchlings, despite never having been in contact with a male. But virgin births have already occurred in a wide range of animals such as sharks, snakes, crocodiles, crustaceans, scorpions and wasps.
Large-scale genome-wide association studies have identified many complex trait loci related to autoimmune, metabolic, and infectious diseases, yet assigning function to non-coding variants remains challenging.
