Researchers Create One-Parent Mouse

Scientists in Japan prove that it is possible to get a live, fertile mouse by activating an egg containing only DNA from female mice. The process of getting an unfertilized egg to start dividing is called parthenogenesis. Although many non-mammalian species reproduce this way, the Japanese mouse is the first known incidence in mammals. NPR's Joe Palca reports.
