      2% of heterozygotes show a malformed leg phenotype. Homozygotes show 3 +/- 1% embryonic lethality and 99+/- 1% of homozygous larvae fail to form pupae. Homozygous embryos have no discernible mutant phenotype.

      24% of br1 ; E(br)420Ebr420/+ flies show a malformed leg phenotype. The predominant leg phenotype in br1/Y ; E(br)420Ebr420/+ flies is short thin tibias and tarsal segments (and sometimes these elements are missing), predominantly in the first leg. 4% of br5/+ ; E(br)420Ebr420/+ flies show a malformed leg phenotype. 21% of E(br)420Ebr420 Rho1J3.8 double heterozygotes show a malformed leg phenotype in at least one leg. 2% of E(br)420Ebr420 Rho1k02107b double heterozygotes show a malformed leg phenotype in at least one leg. 1% of E(br)420Ebr420 Rho1E3.10 double heterozygotes show a malformed leg phenotype in at least one leg. 3% of E(br)420Ebr420 RhoGEF204291 double heterozygotes show a malformed leg phenotype in at least one leg. 6% of E(br)420Ebr420 RhoGEF211-3 double heterozygotes show a malformed leg phenotype in at least one leg. 15% of E(br)420Ebr420 zipEbr double heterozygotes show a malformed leg phenotype in at least one leg. 2% of E(br)420Ebr420 zip1 double heterozygotes show a malformed leg phenotype in at least one leg. 3% of E(br)420Ebr420 zip33-1 double heterozygotes show a malformed leg phenotype in at least one leg.
