Scientists in China breed healthy mice from two females


“We also revealed some of the most important imprinted regions that hinder the development of mice with same sex parents, which are also interesting for studying genomic imprinting and animal cloning.”

The scientists conducting the study, published in the journal Cell Stem Cell Thursday, said they were interested in answering why some reptiles, fish and amphibians can reproduce with one parent of the same sex, but others cannot.

The idea of “designer babies” — in which parents can choose genetic traits — is one example, but some have warned that editing individual human genes could affect the gene pool in future generations and carry unintended consequences.
