Articles like this one tend to lead to speculation about simulating the whole embryology etc so that you can tell what someone looked like starting from their genome. I've been taking the position that a simulation capable of doing that is unlikely because DNA does not work like that - it is not so much a blue-print as a recipe ... and that is probably going a tad far. However, I am hard pressed to support this idea, and the state of knowledge has certainly changed since I last looked at this (early 90's - where it was generally considered doubtful that you could sequence fossil, or just very old, DNA.) Identical human DNA does lead to identical twins ... but they tend to share a womb as well. Would the genetically identical fetuses develop identically in different wombs? How different can genetically identical twins get?
