Searching for Intelligence in Our Genes
... Plomin suspected that he needed more genetic markers to find intelligence genes. When eggs and sperm develop, their chromosomes swap segments of DNA. The closer two segments of DNA are to each other, the more likely they are to be passed down together. But in Plomin’s early studies, millions of DNA ...
