Genetically determined eco-morphological differentiation between color morphs. There is significant body shape and lower pharyngeal jaw (LPJ) shape differentiation between sibling color morphs raised in the same environment (n = 79 gold, 28 dark). The direction of body shape and LPJ shape differentiation was similar to that observed in nature (Fig. 2a and b); gold siblings had larger heads and rather robust LPJ morphologies compared to dark siblings. Scale factor = 10
