German (Austrian?) geneticist Volkmar Weiss has just pointed out that the effect of the recently identified skin color gene SLC24A5, which makes the difference between the white race and other races (See here), is more than skin deep. SLC24A5 is also active in the brain (See here).
Given the statistical linkage between IQ and skin colour (See for instance the Table below), that should not really be too surprising but there are none so blind as those who will not see. The Table is from an article by Donald Templer and Hiroko Arikawa that is in press at the journal Intelligence.
There are more details and some commentary about the article from which the table above is taken here but you need to scroll down to get to it. And see here for some interesting comments on Volkmar Weiss's observation.
