Fig 5 Hybrid and backcross progeny phenotypes of <italic>D</italic>. <italic>quagga</italic> and <italic>D</italic>. <italic>kyathit</italic>.

(A) Pattern variation morphospace showing locations of parental D. quagga and D. kyathit, F1 hybrids, and backcross progeny (BC_a). Images of D. quagga and D. kyathit patterns are details of the same individuals shown in Fig 2 and the F1 hybrid shows a typical pattern in this cross. (B) Principal components (PC) of phenotypic variation in BC_a progeny with percent variance explained noted in parentheses. Melanized element count and perimeter refer to entire spots or stripes. Melanized element coverage refers to total area covered by melanized elements relative to total imaged flank area. Likewise, melanophore and xanthophore densities were calculated relative to total area. Melanophore and xanthophore pigment refer to areas of contracted pigment granules, rather than entire cell sizes. For sex, arrow points towards values typical of males. NN, nearest neighbor.
