Fig. 11. Melanophore and iridophore patterns in tester duchamp mutant
hybrids. (A,B) Different illumination of the same fields of view reveals
melanophore organization (A,C) and iridophore organization (B,D). (A,B) Tester
duchamp hybrids for D. dangila exhibit clusters of
melanophores (arrows) with iridophores (arrowheads) organized around these
clusters, as for hybrids of the D. rerio species group. (C,D) Tester
duchamp hybrids for D. albolineatus typically do not form
clusters of melanophores (arrows), and iridophores (arrowheads) are poorly
organized. Scale bars: in A, 200 µm for A,B; in C, 200 µm for C,D.
