Figure 1From: Association of genome variations in the renin-angiotensin system with physical performanceDiagrammatic representation of the 16 allelic combinations among male/female controls and athletes. The 16 allelic combinations resulted from all possible combinations of the eight different polymorphic alleles studied (ACE (I, D), LEP (G, A), BDKRB2 (+9, −9) and AGTR1 (A, C)).Back to article page
