Realised heritability for downward selection on wing area, cell area and cell number of the four populations.

	FEMALES			MALES
	Wing Area	Cell Area	Cell Number	Wing Area	Cell Area	Cell Number
Belem	0.677	0.216	0.617	0.531	0.463	0.488
Madagascar	0.646	0.643	0.426	0.206	0.415	0.787
Paris	0.362	0.616	0.639	0.288	0.527	0.527
USA	0.718	0.634	0.766	0.696	0.699	0.533

For each line, the realised heritability was calculated as the coefficient of the regression of the trait response on cumulated selection differential.
