    Identical twins, yes. You can have multiple eggs fertile at the same time. Two of my childhood friends were a boy and girl who were twins, obviously look quite different lol

      Thanks for the knowledge! I’ve been walking around knowing that Twins and Identical Twins are different; yet thinking that sex differences were developed post fertilization, like we do some in-vitro reptile shit, hahaha

      Mental apologies to my AP bio teacher, who probably taught me better! He took great pleasure in publicly slaughtering transphobic ideology, before it was cool.
