Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
    Phenotypic Data
    In combination with other aberrations
    NOT in combination with other aberrations

    Homozygous females are sterile, laying very few or no eggs; no females produce more than 10 eggs and the average number of progeny from females is 0.2 +/- 0.1. Those eggs that are laid have an overall percentage hatching rate that is comparable with controls. The ovaries of 3-4 day old mated homozygous females have 2 or 3 mature eggs per ovariole (wild-type ovaries have one mature egg per ovariole). The ovaries of 1 day old homozygous females have no detectable gross abnormalities in the nurse cells, egg chambers, ring canals or overall morphology. Wild-type males mated to homozygous females have courtship indices higher than those of wild-type males mated to control females (65.8 +/- 9.3% vs 42.4 +/- 5%). The duration of copulation for the two types of cross is comparable. The rate of ovulation of homozygous females is dramatically lower than that of control females
