a
Phenotypes (at 29°C) were scored as follows: two or more ectopic veins, ++; one ectopic vein, +; and wild-type vein pattern, −. Numbers are expressed as percentages of the total wings examined for each genotype.
b
Df(2L)cl-h3/+ heterozygotes exhibit a fully penetrant ectopic wing vein phenotype. In combination with snr1E1, the ectopic wing vein phenotype was strongly enhanced relative to control sibling flies, with the strongest effects posterior to the L5 longitudinal vein.
