mirror twins
Anatomically reversed duplicates
Mirror twins are identical twins whose features are asymmetrically reversed, as if one were the other's reflection.
One may be left-handed while the other is right-handed, or birthmarks and hair whorls may appear on opposite sides.
The phenomenon occurs when the fertilized egg splits relatively late in development.
