Many germ cells remain associated with the basal surface of the gut, instead of moving into lateral mesoderm. Those germ cells that do leave the PMG often appear disorganised within the mesoderm and do not correctly navigate toward the somatic gonadal precursors (SGPs). The germ cells that do detach from the gut will often continue to migrate past the lateral mesoderm and into the ectoderm. There is always a small number of germ cells in each mutant that are able to associate correctly with SGPs. The number of gonadal mesodermal cells is reduced in stage 14 embryos.
