Scientists Successfully Breed Mice From Two Females Scientists at the Chinese Academy of Sciences say it was done using a new type of gene editing technology. The feat may help researchers better understand mammalian reproduction. The process still carries significant <br />ethical and safety questions. In the study, a total of 29 bimaternal mice were produced using 210 embryos. Researchers said some of them still <br />showed "defective features." Despite the potential of the latest study, scientists say the technology just isn't ready for practical application. King's College London, via statement
