Approximately two-thirds of hemizygous male embryos die prior to hatching, while the remaining male hemizygotes die during early larval stages.
Eggs derived from females carrying homozygous germline clones are partially deformed or deflated and no larvae hatch from these eggs.
Bap601/+ completely suppresses the position effect variegation at the w locus which is caused by In(1)wm4h.
Bap601, sisA[+]/sisA1, upd1sisC-1/os[+] has partially lethal - majority die | dominant | maternal effect | female limited phenotype
Bap601, sisA[+]/sisA1 has partially lethal - majority die | dominant | maternal effect | female limited phenotype
Bap601, Df(1)sc19/+ has partially lethal - majority die | dominant | maternal effect | female limited phenotype
Bap601, Df(1)sc10-1/+ has partially lethal - majority die | dominant | maternal effect | female limited phenotype
Bap60[+]/Bap601 is an enhancer of humeral bristle phenotype of brm2
Bap60[+]/Bap601 is an enhancer of humeral bristle phenotype of brm2, trx[+]/trxE2
Bap60[+]/Bap601 is an enhancer of humeral bristle phenotype of mor1
Bap60[+]/Bap601, akirinEP906 has larval somatic muscle cell phenotype
Stage 16 Bap601/+ ; akirinEP906/+ double heterozygous embryos show disruption of the somatic muscle pattern (20.2% of embryos have missing, misattached or duplicated muscles in at least 2 hemisegments).
The penetrance of the loss of humeral bristle phenotype seen in brm2/+ flies is increased by Bap601/+ from 7% to 14%.
5% of brm2 trxE2 double heterozygotes show loss of humeral bristles. The penetrance of this phenotype is increased to 15% by Bap601/+.
Bap601/+ ; trxE2/+ double heterozygotes do not show loss of humeral bristles.
The penetrance of the loss of humeral bristle phenotype seen in mor1/+ flies is increased by Bap601/+ from 3% to 7%.
The penetrance of the antenna to leg transformation phenotype seen in AntpNs/+ flies is slightly suppressed by Bap601/+ from 100% to 92%.
The antenna to leg transformation phenotype seen in Antp73b/+ flies is not suppressed by Bap601/+.
Maternal heterozygosity for Bap601 reduces the viability of female offspring which are doubly heterozygous for sisA1 upd1sisC-1.
Maternal heterozygosity for Bap601 reduces the viability of female offspring which are heterozygous for sisA1.
Maternal heterozygosity for Bap601 reduces the viability of female offspring which are heterozygous for Df(1)sc19.
Maternal heterozygosity for Bap601 reduces the viability of female offspring which are heterozygous for Df(1)sc10-1.
Bap601 is rescued by Bap60Act5C.PM
