Cichlid species distributions and the frequencies of LWS and RH1 alleles. a Species distributions by depth are shown in each column. The positions of the columns of species are identical in (a)–(c). Frequencies of b LWS and c RH1 alleles in the ten species. The names of the alleles correspond to those in Fig. 2b and c, respectively. The number of total alleles per species is shown at the top of the columns. Abbreviations for the species names are shown in Fig. 1b
