Homozygous clones induced in the follicle cells result in defects in border cell migration; the border cells fail to initiate migration and remain at or near the anterior tip of the egg chamber even in stage 10.
Selected as: a mutation that causes defects in border cell migration when homozygous clones are induced in the follicle cells. The mutant phenotype may be a synthetic phenotype caused by two mutations that are sufficiently far apart to recombine at high frequency.
