I heard that identical twins can only be the same sex. Does anyone know if that's a myth or if it's true?
Oh wow, I've never even known this. Thanks for the infoI heard that identical twins can only be the same sex. Does anyone know if that's a myth or if it's true?
Identical twins share the same DNA so they are always boy/boy or girl/girl although there has been VERY rare cases of the egg splitting before the gender has been "decided" and then boy/girl twins resulting.
