Fig 2. Median-joining network for TAS2R38 alleles of Japanese and rhesus macaques.

Each circle represents a different haplotype and is shown along with the allele name. Mf and Mm indicate Japanese and rhesus macaque haplotypes, respectively. Colors within a circle indicate each local population (Table 1), and the size of a circle is proportional to the number of chromosomes. Nucleotide positions of mutations that differentiate alleles are indicated on the network branches. Line styles of branches indicate mutation types.
