In females with slmb^unspecified germline clones 17.4% of follicles exhibit abnormalities: i. 3.7% exhibit features of apoptosis, such as germ cell nuclear fragmentation ii. 9.9% exhibit increased numbers of germ cells iii. 1.7% exhibit decreased numbers of germ cells iv. 2.9% have germ cell nuclei that are heterogeneous in size. In slmb^unspecified germline clones, all oocytes from follicles with extra nurse cells and one single oocyte exhibit five ring canals instead of four, indicating that an extra round of mitosis has occurred. All observed egg chambers with two oocytes exhibit four ring canals per oocyte. Egg chambers with somatic slmb^unspecified follicle cell clones also display a range of defects. Such egg chambers frequently contain two oocytes and extra nurse cells within a single follicular epithelium. Ovarioles often exhibit germaria in which two or more cysts are placed side by side in regions IIb and III. The egg chambers are frequently an aberrant shape and have mispositioned oocytes within the follicle, adopting an anterior or lateral location. Finally, some ovarioles lack interfollicular stalks between adjacent follicles and are instead separated by a layer of epithelial cells. Eggs laid by females in which slmb^unspecified germline clones induced by heat shock exhibit diverse patterning defects. These eggs are often smaller than wild-type eggs and are abnormal in shape. Egg chambers with slmb^unspecified somatic clones generate eggshells with variable dorsal appendage phenotypes. Some eggshells have a dorsalized phenotype, characterized by laterally expanded dorsal appendages, or in more severe cases, by dorsal appendages that surround the entire circumference of the egg. Other eggshells are apparently ventralized with dorsal appendages that are partially or totally fused. Some dorsal appendages are ramified. Additionally, eggshells exhibit a slightly enlarged operculum or a greatly reduced amount or absence of dorsal appendage material.

Follicle cells are disorganised and migrate between the oocyte and the nurse cells in females containing homozygous germline clones. The oocyte is smaller than normal.

Heterozygotes have necrotic areas on the wings.
