The first decision tree and associated rule-set of the continental classifier produced by ETHNOPRED algorithm. The decision tree uses 3 internal nodes (SNPs) acting as decision criterions and 4 external nodes (populations) demonstrating decisions. The number of rules in the relevant rule-base is equal to the number of external nodes of the decision tree.
