Table 2 Results of the mixed linear model ANOVAs (on log-transformed data) with temperature, sex and effect of selection1 as fixed effects and population nested within effect of selection, sex and temperature on the standardised size values of the experimental selected populations and the inbred controls after one generation of mass-breeding for wing area, cell area and cell number.

From: Fitness variation in response to artificial selection for reduced cell area, cell number and wing area in natural populations of Drosophila melanogaster
