Fig. 10. Pattern regulation in fms^174A/fms^blue transheterozygotes. (A) Normal adult melanophore stripes develop in fms^174A/fms^blue individuals reared at 24°C. (B) Xanthophores and melanophore stripes are recovered in fms^174A/fms^blue individuals reared 35°C prior to feeding, and at 24°C thereafter. (C) More frequent breaks in adult melanophore stripes occur in fms^174A/fms^blue individuals reared at 33°C prior to hatching, as compared to fms^174A/fms^blue reared at 24°C prior to hatching, or fms^174A/+ or fms^blue/+ heterozygotes reared at either temperature (temperature x genotype interaction for square root-transformed data: F_1,110=6.33, P<0.05). Shown are unilateral mean numbers of breaks in melanophore stripes per individual (±95% confidence intervals). Scale bar: 500 µm.
