Skin colour is determined by Melanin (which exists in chromosomes, just like every other strand of DNA we have). I think by "dominant chromosomes" you meant genes?
The lower levels of melanin you have, the "whiter" you are.
Michael Jackson's lady friend did not carry a "non-dominant white chromosome", whatever the hell that is. She did carry a white skin colour melanin (meaning she had a low level of it) though, but the chances of her having a baby with a black man, and the baby having completely "white" facial features and also white skin is around 0. In most cases, the baby is quite dark (not as dark as the father though) - on the odd occasion it has a "tan" look. EVEN if it manages to fluke having white skin (which I don't buy for a second) it would still have "black" facial features as Hooper said, and Jackson's kids didn't have this.
Whilst it is true recessive GENES can be carried through on the rare occasion in eyes, that is; a blue eyed mother and a brown eyed father can have a blue eyed child (even though brown is more dominant). In skin, it's very different. Add to the mix that Jackson's ancestry would be black for generations, and generations...
In short; It's no bloody surprise the kids aren't biologically his!
