Scientists analyzed DNA samples from 141,431 pregnant Chinese women, or roughly 1/10,000 of the country’s population

Scientists used modified egg and stem cells to create female mice with two mothers. These fatherless mice grew up to have babies of their own (through more typical means of conception).

Scientists Break the Rules of Reproduction by Breeding Mice From Single-Sex Parents

By tinkering with the genes of sperm and egg cells, it’s possible to breed mice from two females—and even from two males
