Chinese scientists created mice with 2 dads — and they survived to adulthood
Scientists in China have unveiled a new method for breeding mice with two male parents - the resulting babies can survive to adulthood. It is not the first time scientists have bred mice with two dads, but previous attempts did not result in mice that could live to adulthood. The resulting mice had deficits, including shorter lifespans and infertility. The research could result in a better understanding of imprinting disorders, potentially paving the way to treatments that use gene editing to fix them in humans.
