Wing shape index Averages of the relative length (with 95% confidence intervals) of the basal portion of longitudinal vein IV (L1) to the total wing length (WL = L1 + L2) versus karyotype for outbred crosses at the two rearing temperatures. A two-way factorial ANOVA using the shape index as , with karyotype and temperature as fixed effects, and crosses nested within karyotypes, detected statistically significant differences for the main effects (karyotype: female F5,30 = 12.625, P < 0.001; male F5,30 = 9.785, P < 0.001. Temperature: female F1,390 = 30.219, P < 0.001; male F1,390 = 61.835, P < 0.001) but no karyotype Ă— temperature interaction (females: F5,390 = 1.570, P = 0.168; males: F 5,390 = 1.111, P = 0.354).
