The rs1726866(C) allele is the "tasting" allele, and it is dominant to the "non-tasting" allele rs1726866(T), so having one copy is enough to have the bitter tasting ability. If you are a "taster", you're also likely to carry at least one rs713598(G) and one rs10246939(C) allele since, along with rs1726866(C), these three SNPs form the most common tasting haplotype. If you lack these alleles, you're quite likely (~80%) to be a non-taster of bitterness, meaning that foods that may taste bitter to others taste far less bitter to you.[PMID 12595690]
