There is far too much interplay between genes, plenty of which are still unmapped, for us to even begin to hazard a guess at something as complex as facial structure.

I mean, according to my genome, I’m short, black, unable to smell asparagus in my pee, don’t have the photic sneeze reflex, have cystic fibrosis, and am bald - and I’m none of those things. Were it not for the fact that I’m definitely my mother’s son according to the same services (23andme -> promethease) I would have thought they’d mixed up my sample.

Until we actually understand gene expression, we’re just looking at a limited set of inputs and using pretty woolly cluster analysis to correlate with outputs.
