    In combination with other aberrations

    Df(1)os1/Df(1)osUE69 animals have a small eye phenotype, with about 400-450 ommatidia per eye, compared to 750 in wild-type.

    Inferred to overlap with: Df(1)os1.

    NOT in combination with other aberrations

    Homozygous embryos have segmentation defects.

    Defect in the fourth and fifth abdominal denticle belt. This does not produce embryonic lethality as mutant larvae, pupae and sometimes adult can develop lacking the abdominal region. T2, T3 and A8 are sometimes deleted, the head is usually involuted but most head structures are present.
