P{KP} element insertion in the 2nd intron, 279bp upstream of exon 3.
2.6 kb insert at 42.3-43 kb (2nd insert at -3.3 to -2.8 kb retained in revertants) P element at 14C-D
Flies are sensitive to ether (lower concentrations are required for anaesthesia compared to wild-type flies).
hybrid dysgenesis gives partial reversion with loss of insert
Excision of the P{KP} element reverts the phenotype. Order of sensitivity to ether anaesthesia is (most sensitive to least sensitive): parahd8 > parats3 > parats1. Order of sensitivity to heat induced paralysis is (lower temperature for 50% paralysis to higher temperature for 50% paralysis): parats3 > parats1 > parahd8.
