Scientists in China have unveiled a new method for breeding baby mice with two male parents, and the resulting babies can survive to adulthood. This is not the first time scientists have bred mice with two dads; a research team in Japan did so in 2023, using a different approach. In the new study, scientists not only bred two-dad mice that could live to adulthood, but did so in a way that might shed new light on a complex suite of genes whose activity varies depending on which parent you inherit them from. ➡️ https://www.yahoo.com/news/chinese-scientists-created-mice-2-224000269.html
