Re: Come and place your guesses, "angle of the danglers"! Guess genders 13w twins!
27% of identical twins don't share a sac. So says my husband's genetics textbook. Though his 80-year-old grandmother is still in denial that her sons are identical. I should post pictures - they are literally harder to tell apart at age 60 than my mother and her identical, mirror twin. And honestly, I am pretty damn certain that I know my own mother.
