Ovaries carrying germ-line clones homozygous for "ph0" (ph-d504 ph-p504) are normal. When somatic clones homozygous for "ph0" (ph-d504 ph-p504) are induced 4, 6 or 8 days after eclosion, they are rarely detected in the follicular epithelium of the ovary even though large wild-type twin-spots are frequently present. These mutant clones can occasionally be observed in the process of being 'expulsed' from the follicular epithelium. Despite this, ovaries containing these clones contain fused egg chambers and apposed egg chambers not separated by an interfollicular stalk. Where stalks are present they are sometimes abnormal - consisting of more than a dozen cells in 2-3 lines rather than five to seven cells organized in a single line as in wild-type. Only some of these abnormal stalks contain (surviving) mutant cells. Polar follicle cells are generally unaffected, although additional polar cells are very occasionally present in egg chambers of stage 5 or later. Small somatic clones of "ph0" (ph-d504 ph-p504) homozygous cells can be recovered in the germarium. In region 2b/3 of the germarium, these cells fail to extend long, thin cell processes centripetally as their wild-type counterparts do, but instead remain at the periphery with an abnormally rounded morphology.
