    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.

        Large mutant clones in the eye result in a total lack of eye development.

        (Cadigan et al., 2002)

        XX eggs laid by homozygous females die at the embryonic stage at the nonpermissive temperature (22oC and above). The variegated morphology of the In(1)fB15 chromosome is suppressed in males derived from daunspecified/daunspecified mothers.

        (Chakrabarti et al., 1995)

        Females heterozygous for Df(1)N19 that are derived from daunspecified/+ mothers show reduced viability at 29oC.

        (Sanchez et al., 1994)

        Triploid intersexes that are the progeny of homozygous da- mothers are masculinised.

        In(1)fB15 rescues the lethality of XX eggs laid by homozygous females at the nonpermissive temperature; homozygous In(1)fB15 females derived from daunspecified/daunspecified mothers survive.

        Analysis of triploid flies shows that the lethal da maternal effect is depends on the X/A balance, rather than the absolute number of X chromosomes.
