None of his children from Kris resemble him/her

That can be fixed with surgery.

If you can use surgery to transform a man into a woman, why not doing the same with your kids into kids that resemble you? XD

At this stage you can't really tell because both of his daughters have had their facial and body skin transfigured.

If you look at older (younger) pictures of them while their older siblings (Kardashians) you can see how different they look BUT I think they resemble their half-siblings from Bruce's previous marriages.

I think Bruce is one of those humans that don't pass on their genetic traits for face/hair/body type very well even though he's father six kids so far. All of his kids resemble their mothers for the most part.
