Fig 2. Coding region SNPs, genotypes and haplotypes of the 25 TAS2R genes.
Light grey boxes indicate homozygous major genotypes or haplotypes, i.e., most common; black boxes, homozygous deleted genotypes or haplotypes, i.e., whole-gene deletion; each other colour box specifies a different genotype or haplotype, homozygous or heterozygous, as detailed in the colour bar. Haplotypes were named according to previous nomenclature or according to their respective allele frequencies in our subjects; the most common haplotypes receiving the smallest number [26]. Chromosomal assignments are specified for cSNPs and TAS2R loci. (A) cSNP genotypes by subject; (B) TAS2R genotypes by subject; (C) genotype frequency by cSNP site; (D) genotype frequency by TAS2R locus; (E) allele frequency by cSNP site; (F) haplotype frequency by TAS2R locus.
