Mosaic stage 10 RalaPG69 oocytes show a complete lack of border cell migration.
Mosaic RalaPG69 clones where the outer border cells are mutant but the two polar cells are wildtype show normal formation of the border cell cluster, and normal border cell migration.
When one of two polar cells is mutant for RalaPG69, a reduced number of border cells are seen in the cluster, and it does not migrate.
When both of the polar cells are mutant for RalaPG69, almost no outer border cells are recruited.
Some polar cells, but not other mutant follicle cells, show increased cell death when homozygous mutant for RalaPG69.
Adult hemizygous males die during embryogenesis from stage 13 through the first-instar larval stage.
