Figure Caption
Fig. 1
crasher mutants have fewer and lighter melanophores. (a, a') Lateral (a) and dorsal (a’) view of crasher siblings with typical the wild-type (WT) phenotype at 3 days postfertilization (3 dpf). (b, b′) Lateral (b) and dorsal (b′) view of homozygous recessive (mutant) phenotype. Arrowheads indicate punctate melanophores. (c) Melanophore count boxplot at 3 dpf. Mutants average 25% fewer melanophores (μ = 188, SD = 20.4) than WT siblings (μ = 255, SD = 20.9). (Student's t-test, t[28] = −8.87, p = 1.27 × 10−9***). (d) Iridophore count boxplot at 3 dpf. Mutants vary more (median = 25, interquartile range [IQR] = 23 to 29.5), but have similar iridophore numbers as WT siblings (median = 28, IQR = 22–29) (Mann–Whitney U test, W = 11.05 × 101, p = 0.95). Scale bar is 1 mm.
