I am not sure that this should be legal. Seems to me, and it states in the article as well, that this is getting a tad too close to human cloning for my tastes. Yes, there is genetic material found in the cytoplasm of a cell, namely the DNA found in the mitochondria. So basically, they are mixing DNA from three different adults. The mixing bowl analogy would be better suited when there is a surrogate mother involved...in that sense, the mixing bowl would be the womb, and nothing else.
This procedure causes an child to be born with three differnt kinds of DNA, which could cause problems scientists have never even run into. It raises an interesting scientific question about what would happen, though. As of now, your nuclear DNA is a mix of your parents DNA, while mitochondrial DNA is only inherited from your mother. Seems to me, that due to the fact that you can only inherit it from your mother, cellular machinery may rely on that assumption in some way.
Either way, its too close to human cloning, which is shady as hell:)
