Scientists use gene editing to produce mouse pups with same-sex parents

Scientist in China said they used CRISPR gene editing to breed mice with same-sex parents, shedding light on a biological mechanism that prevents reproduction in the absence of both maternal and paternal DNA. The pups with two mothers grew to adulthood and were able to bear pups of their own, but none of the bipaternal pups survived to adulthood, the researchers reported in Cell Stem Cell.
