    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.

        Homozygous D. melanogaster males court D. pseudoobscura females.

        Homozygous D. melanogaster males court conspecific D. melanogaster males. They also court D. simulans and D. yakuba males, but do not court D. virilis males.

        (Fan et al., 2013)

        In contrast to control wild-type D. melanogaster males, homozygous D. melanogaster males court D. simulans, D. virilis and D. yakuba females. The mutant males show the entire range of courtship preceding copulation towards these females. The mutant males copulate with conspecific D. melanogaster females.

        In contrast to wild-type D. melanogaster males, homozygous D. melanogaster males court oenocyteless D. melanogaster females which have been coated with either z-7-tricosene, z-9-tricosene or z-11-pentacosene.

        Both wild-type and homozygous D. melanogaster females reject courtship attempts of tarsiless D. simulans and D. yakuba males.

        D. melanogaster males expressing TrpA1Scer\UAS.(B).cKa under the control of Scer\GAL4Gr32a.3.776 in a homozygous Gr32aunspecified background court D. virilis females at the permissive temperature for TrpA1 (this is the phenotype seen in homozygous Gr32aunspecified males in a wild-type background). However, at an elevated temperature (which activates TrpA1), these males court conspecific D. melanogaster females but not D. virilis females.
