The induction of (near) whole-eye hdc^del clones leads to significantly larger eyes than upon the induction of (near) whole-eye control clones.

hdc^del homozygous eye disc clones are much larger than their twin-spots under a protein-poor diet, but nor under nutrient rich diet. This correlates with adult eyes bearing hdc^del clones being mainly composed of mutant tissue and being significantly larger than controls under a protein-poor diet, but not under nutrient rich diet. hdc^del homozygous eye disc clone cells show accelerated cell cycle progression, as mutant second mitotic wave cells are more anterior than neighboring wild-type controls; this is more evident under a protein-poor diet.

Wing disc clones are larger than their twin-spots under a protein-poor diet.

Both hdc^del adult wing margin bristle and pupal retina clones do not show cell size changes compared to controls under both nutrient rich and protein-poor diets.
