What do people think are the odds that we'll find specific genes that are markers for IQ?
(I assume that, just like with cancer, genes are "risk factors", not on-off switches, and how they're expressed depends somewhat on environment and behavior. But the equivalent of BRCA for IQ would still be really important.)
We already know a number of things about the genetic basis of intelligence - e.g. try searching for ASPM, NR2B, HAR1 and PYDN.
Current research suggests it's hideously complex, and heritable characteristics with that level of complexity don't tend to have simple markers.
then the Chinese may be disappointed.
