In assisted pregnancy, if one fertilized egg is returned to the mother’s uterus then this egg may divide and produce identical twins in the womb.

   Are identical twins genetically identical?

   • This does seem strange given that identical twins stem from a single ovum that splits in the days after fertilization takes place. Identical twins come from a single ovum and are assumed to be 100% genetically identical. If handedness has a strong genetic origin, then identical twins should always show the same handedness side.
