Science: Scientists Make Mice With Two Dads

Scientists have managed to create mice with two biological fathers, which could lead to implications for same-sex reproduction in the future. Researchers at Kyushu University, in Japan, were able to create lab-grown egg cells by using the skin cells of male mice. While creating mice with two biological fathers was technically possible prior to the achievement, it involved a series of elaborate steps, including genetic engineering. After creating stem cells from eight-week-old male mice, scientists manipulated the genetic code of the cell to create a mature egg. After successful cultivation, the eggs were fertilised and implanted into a surrogate mouse, … Read more

SCIENCE: Making Mice With Two Dads

For the first time, researchers have directly created mice with two dads. The mice weren’t able to survive for more than a day or so after birth, but coaxing an embryo made from the DNA of two dads all the way through fetal development was no small feat. It was much harder, the researchers found, than making mice with two moms. The findings help explain why mammals can’t reproduce with only a single parent. They also may help explain why those animals that can reproduce alone, such as some amphibians, are almost always female. The barrier to single-sex reproduction, said … Read more
