    In combination with other aberrations

    Lethal in combination with Df(2R)Px5.

    Df(2R)Px1/Df(2R)Px2 lethal Df(2R)Px1/Df(2R)Px5 lethal

    NOT in combination with other aberrations

    The Df(2R)Px1 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).

    The tracheal phenotypes previously reported for this deficiency in FBrf0051997 and FBrf0072461, where the primary branches are disrupted and discontinuous, are due to the deletion of a gene other than bs, or more than one gene in the region.

    Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

    Wing veins of heterozygote with px-like or Dl-like thickenings, most often near posterior crossvein and free fragments of vein, most often in third posterior cell; L4 vein bent near margin. Wings smaller and narrower than wild type and dusky textured. Closely resembles bs. Expression more extreme in female; enhanced by cold (19o). homozygous lethal as embryo (Li, 1927).

    Other Comments

    Complementation tests reported for Df(2R)Px1 may have used a Df(2R)Px2 stock. The Mid-America Stock Center stock 1779 and the Bloomington Stock Center stock 750, which were labeled Df(2R)Px1, were in fact Df(2R)Px2 stocks. The mix-up predates 1991.

    FlyBase curator comment: See personal communication from Bloomington Drosophila Stock Center, 2003.8.1, for note about possible confusion between Df(2R)Px1 and Df(2R)Px2 stocks.
