Okay…it was mouse, using stem cell technology, but the headline would be no less striking with the addition of “mouse dads.” This is literally A Brave New World.
Using stem cell technology, Texas researchers have created mice who have two genetic fathers – an advance that could give same-sex couples their own genetic children one day.
Rather than have the usual chromosomal assemblage from a father (XY) and a mother (XX), these mouse babies carry daddy-only chromosomes from two males.
“It has been a weird project, but we wanted to see if it could be done” in mice, says developmental biologist Richard Behringer from the University of Texas M.D. Anderson Cancer Center.
