(A) Schematic illustrating where idealized patterns fall in a morphospace defined by DV (dorsoventral) and AP (anteroposterior) pattern variation of melanized elements. Diagonals indicate different log₂ values for the ratio of DV variation: AP variation. (B) Mapping of pattern phenotypes in this morphospace revealed overlap of striped D. rerio, D. quagga, and D. nigrofasciatus, and their difference in morphospace from spotted D. kyathit or D. tinwini. Additional species occupied distinct regions of morphospace as well. Images of other Danio species have been published previously [4,16,19]. Points denote individuals and shapes denote observed phenotypic range. (C) Several single locus mutants of D. rerio lie between D. quagga and D. kyathit, or in the vicinity of D. kyathit. These phenotypes arise from null or hypomorphic alleles [22,27, 37,38,42,51,62–64,76,85,86,98–101], though aqp3a results from an activating mutation [53], and some mutants have yet to be characterized molecularly (cezanne, chagall, duchamp, ocelot) [8,84]. Points for each mutant denote individuals, or averages when images of multiple individuals were available.
