Table 1 Results of ANOVA models for the cell sizes of legs, wings, eyes and flight muscles in four genetic groups of Drosophila melanogaster (rictorΔ2 mutant and its control, Mnt1 mutant and its control) without (a) and with the thorax length treated as a covariate (b).

From: Systemic changes in cell size throughout the body of Drosophila melanogaster associated with mutations in molecular cell cycle regulators

  1. The analysis included two contrasts, in which each mutant type was compared with its control. Data for legs, wings and eyes were collected for both sexes, while data for flight muscles were collected only for males.
