Fig. 1. Histamine, dopamine and 5-HT are reduced in the heads of white, brown and scarlet mutants relative to wild-type heads. (A) Histamine content, means of means from 10–13 samples for each genotype. (B) Dopamine content, means of means from 10 samples for each genotype. (C) 5-HT content, means of means from 10 samples for each genotype. All three mutants differ from Oregon-R wild-type for all three amines: *P<0.0005 (t-test).
