hop25/hop33 non-fused egg chambers often have extra polar follicle cells (having 3 or 4 cells rather than the normal number of 2 polar cells at both the anterior and posterior ends of the egg chamber). At stage 8/9, 93% of egg chambers have extra polar cells at the anterior end and 67% of egg chambers have extra polar cells at the posterior end. The number of interfollicular cells is reduced. The extra polar cells do not appear to be due to continued proliferation of the polar cell population.
70% viable in transheterozygous combination with hop25.
Paternal rescue of the maternal effect. Germline clone analysis demonstrates that embryos have one abdominal segment missing and A4 appears wider than wild type, and partial or complete fusion of T1 and T2.
hop33/hop25 has partially lethal phenotype, enhanceable by upd1YM55

Fully complement hop25.
