By maternal environment, do you mean just home/rearing environment attribute to the mother rather than father, or the womb environment/dam effects? The former does exist (you can do neat designs these days like looking at IGEs of just genes in the mother but not father) but influences stuff like EDU much more than IQ; a clone is already maxed out on EDU potential so we don’t care if the adoptive placement gives mothers less keen on education than von Neumann’s parents were. Womb environments have also been measured, I think through designs like you suggest (or was it children-of-twins designs? I forget) and found to be generally unimportant despite some hype. After all, whether you correlate against the mother or father, or second-degree relatives in any direction, the correlations are similar...
Thanks for the answer! By maternal environment I indeed meant the latter rather than the former, i.e. womb environment etc., i.e. the part one might not be able to duplicate when cloning. But if that hardly matters in the general population, I guess that’s not much of a worry.
