Interestingly, even the website for the twin study at U of WA specifically states that idential twins share ALL of their genetic material thus, in the rare circumstance of monozygotic boy/girl twins, they would not be referred to as "idential" at all since they don't share all of their genetic material There are NO IDENTIAL boy/girl twins yes they can be identical, mad I know BUT there is a lady Ange on the AMM She has b/g twins was told they were ID all through pg and then they were born one girl and one boy and she was very surprised; 30% of di/di twins are identical Whether they have one placenta or two and/or one amniotic sack or two has to do with the timing of the egg splitting I have two sisters with twins Both Sets are Di/Di Both got genetic testing after they were born Both sets are identical!!
