    Description

    FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.

        Heterozygotes are viable and can fly (as judged from their behaviour when released from an open vial).

        (Kolmerer et al., 2000)

        Muscle cells of mutant embryos contain as few as 1 to 3 nuclei per cell, compared to 5 to 20 per cell in wild-type embryos.

        (Machado and Andrew, 2000)

        Mutant embryos have an increased number of phagocytes which are not normally seen in wild type.
