  • a Phenotypes of female siblings; 0 indicates wild-type phenotype, 10 indicates maximal bithorax mutant phenotype; errors are standard errors. The number of flies scored ranged from 20 to 39. su(Hw)e2 partially suppresses the bx34e gypsy insertion so that su(Hw)e2 bx34e flies display a phenotype between 2 and 2.5 in the absence of other mutations. See Figure 3 for sample phenotypes. Virtually identical results were obtained with the male siblings.
