Jon and Kate plus 8? why do they look Asian?

It all has to do with genetics, which are never predictable. In Brandon Lee's case, he must have gotten his mother's genes in terms of skin color and such. The Gosselin children all got Jon's Korean skin. I'm not positive about this, but I've always thought that ethnicities with darker skin tones were usually ped down to the offspring. So if an African and a Caucasian had a baby, the baby would most likely be black. I think the same rule goes with Asian.
