bs[+]/bs2R-19 is an enhancer of visible | recessive phenotype of mys8
bs[+]/bs2R-19 is an enhancer of visible | recessive phenotype of mysb9
bs[+]/bs2R-19 is an enhancer of wing phenotype of mys8
bs[+]/bs2R-19 is an enhancer of wing phenotype of mysb9
Shows a strong genetic interaction with mys8 and mysb9; the frequency of wing blisters in mys8 or mysb9 single hemizygotes is increased if they are also heterozygous for bs2R-19.
