Identical (monozygotic) twins are always of the same sex because they form from a single zygote (fertilized egg) that contains either male (XY) or female (XX) sex chromosomes. ... A set of boy/girl twins can only be fraternal (dizygotic). Boy/girl twins can not be identical (monozygotic).I was telling my mate last night that I finally achieved my ultimate fantasy in shagging identical twins.

''Yes'', I replied, ''Samantha had a cracking pair of tits and Simon had a beard.''
Wonder what he was shagging, then?Identical (monozygotic) twins are always of the same sex because they form from a single zygote (fertilized egg) that contains either male (XY) or female (XX) sex chromosomes. ... A set of boy/girl twins can only be fraternal (dizygotic). Boy/girl twins can not be identical (monozygotic).
