    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.

        There is little difference in the amount of brown pigment in the eye of female stunspecified/stunspecified; we(g)/Df(1)N-8 and stunspecified single mutants.

        (Lloyd et al., 2002)

        dcm1; stunspecified double mutants have orange eyes.

        (Aguado et al., 1988)

        Eye colour: dark yellow to orange in combination with g2.
