Hypothesis
Populations which have remained near their origin will show a lower proportion of long alleles of DRD4 than those that migrated further away (312).
Note
This finding was consistent across all six migration routes. The proportion of long alleles increased by 4.3% for every 1,000 miles of macromigration.
