Src42A6-1 has adult thorax phenotype, enhanceable by shg[+]/shgg317
Src42A6-1, shgR6 has embryo | dorsal closure stage phenotype
Src42A6-1, arm4/arm[+] has embryo | dorsal closure stage phenotype
Src42A6-1, arm4 has embryo | dorsal closure stage phenotype
Unlike either single mutant, shgR6; Src42A6-1 double mutant embryos show a dorsal open phenotype. Src42A6-1 notum phenotypes are enhanced in a shgg317/+ background; in some Src42A6-1; shgg317/+ flies the right and left halves of the notum appear completely separated. The majority of arm4/+; Src42A6-1 embryos show a dorsal open phenotype.
