No monozygotic twins always have same sex/gender

Answered by apu3

The terms identical and fraternal don't describe what the twins look like, but actually how they form. 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. Therefore, boy/girl twins are always fraternal or (dizygotic); they can only form from two separate eggs that are fertilized by two separate sperm. Fraternal twins can be either two girls, two boys, or one of each.
