        Detailed Description
        Statement
        Reference

        An average of 0.4 PGCs are left outside of the midgut in shgA9-49 mutants, with 25% of the embryos showing PGC adhesion defects. This phenotype is dependent on the maternal genotype, as a paternal wild-type copy does not alleviate the phenotype.

        Statement
        Reference

        Loss of maternal shgA9-49 is unable to rescue the germ cell migration defects seen in embryos derived from females carrying wun49 wun2EP2650ex34 germline clones crossed to Df(2R)wun-GL males. Germ cell dispersal can be seen at stage 10.
