Fig. 2From: The MC4R SNPs, their haplotypes and gene-environment interactions on the risk of obesityDifferent types of interaction dendrogram for SNP-environment (a) and haplotype-environment (b) interactions on the risk of obesity. Blue color, strong redundancy interaction; green color, weak redundancy interaction; orange color, synergy. The elements with strong interaction are close to each other at the leaves of tree, and the elements with weak interaction are far away from each otherBack to article page
