23% of embryos carrying enhs.PH, given a mild heat shock (7 minutes at 37oC) produce severely defective cuticles, with multiple fusions or deletions of denticle belts.
Ectopic expression after 3 hours of development causes pattern defects in each segment.
One hour heat pulse of P{HS-en.G} at 100 hours AEL in oc1 individuals causes the reappearance of ocelli.
enhs.PH has ventral denticle belt phenotype, suppressible by hthMeis1-P2
enhs.PH has embryonic/first instar larval cuticle phenotype, suppressible by hthMeis1-P2
The percentage of embryos given a mild heat shock (7 minutes at 37oC) producing severely defective cuticles (multiple fusions or deletions of denticle belts) is reduced (23% to 7%) when both parents are heterozygous for hthMeis1-P2.
