Nonfunctional allele genotypes for 20 OR genes in 145 individuals. The genes have been selected to maximally span the genotype range. Individuals are sorted by ethnicity as in Figure 4. Allele statuses are: intact (I), nonfunctional SNPs/indels (S), bi-allelic deletion CNV (D) . Colors indicate genotypic combinations. The full matrix with all 177 ORs in 145 individuals is shown in Additional file 1: Figure S7.
