Colour patterns in Danio fish and interspecific hybrids.a Colour pattern of zebrafish, D. rerio. bD. rerio Meox1 (choker) mutants, which lack a horizontal myoseptum. cD. aesculapii. dD. tinwini. e Hybrid between D. rerio and D. aesculapii and f hybrid between D. rerio and D. tinwini. gD. choprae. hD. margaritatus. i Hybrid between D. rerio and D. choprae, j and hybrid between D. rerio and D. margaritatus. k Hybrid between D. aesculapii and D. choprae. l Hybrid between D. tinwini and D. margaritatus. mD. erythromicron. n Hybrid between D. rerio and D. erythromicron. o Hybrid between D. aesculapii and D. erythromicron. p Hybrid between D. aesculapii and D. margaritatus. qD. dangila. r Hybrid between D. rerio and D. dangila. All pictures are representative for the corresponding species or hybrids; for the variability of hybrid patterns see Supplementary Fig 1. Please note that not all panels are shown to the same scale; the sizes of the fish are ~18 mm (D. margaritatus and D. erythromicron), 24 mm (D. tinwini), 30 mm (D. choprae), 35 mm (D. rerio, D. aesculapii) and 75 mm (D. dangila).
