China-based BGI could help expecting parents decide on the "smartest" embryo to give birth to.
BGI's cognitive genomic division is mapping out the genes of math geniuses to figure out which genes make people smart.
It turns out that a lot of kids are within 13 IQ points of their mom and dad combined, on average. But two out of three children end up being a lot smarter.
And believe it or not, you're basically as smart as your genes, researchers say.
