Types of twins

[PinKDiGiT18]

Always interesting to see if it's a trend for identical twins come out identical in this regard as well.

I know a pair of female identical twins who are ESE-Fe and possibly IEE-Ne. Benefit.

A pair of male fraternal twins: one is ESI-Se, the other is LIE-Te. Duals.

A pair of relatives who are sororal twins: one is ESE-Si and I think the other is SEI-Si. Mirrors.

Ironically, I also know a pair of fraternal twins who are both ESE-Si; present as the same person but one is a guy and one is a girl.

If you're a twin or know a set of twins, drop your/their types.
