    In combination with other aberrations

    fliIFLI Df(1)16-129/fliIFLI Df(1)2/19B individuals are 100% viable and 98% of survivors can fly normally.

    Lethal in combination with Df(1)16-129.

    Lethality is complemented by Dp(1;Y)59k9-4.

    The fliI gene on the Df(1)2/19B chromosome has an 5.4kb insertion, which is probably a mobile element.

    Df(1)2/19B is not deleted for the fliI locus but fails to complement fliI alleles on account of the linked fliI2:19B.
