Researchers at University of Texas M.D. Anderson Cancer Center created mice that are the genetic product of two fathers. They first engineered a female mouse whose eggs contained the DNA from a male. When the female was mated with another male, the offspring had genetic contributions entirely from two males.
The study appeared in the peer-reviewed journal Biology of Reproduction. The study describes the technique as "a new form of mammalian reproduction" that could potentially be used to improve livestock breeds or preserve endangered species. More provocatively, the authors argue that if certain technical hurdles can be overcome, "then some day two men could produce their own genetic sons and daughters." But those technical hurdles are extremely high.
