If done by surrogate there is a whole world of epigenetics we are just getting into that can have an effect on embryo growth as those turn your genes on or off in the womb and are provided by the surrogates mother. It wouldn't surprise me if they looked a little like the surrogate.
There's a lot they don't know yet.

But all the theories here are equally plausible.
