You complain to me
The mice that he survived and male genetic fathers have survived from puberty for the first time. However, achieving this requires a large -scale genetic amendment, among other things, which can never be tried in people.
These are not the first mammals with parents of the same sex-mice with two nations first It was created in 2004And while she was unusually small, they appeared Live longer Of usual. But the creation of mice with two parents has proven to be more difficult.
