Only 1.% of flies expressing paraL1699F.Scer\UAS.1-1 under the control of Scer\GAL4elav-C155 show bang-sensitive paralysis. The average recovery period for those flies that do paralyse is 33 seconds (which resembles the recovery time of parabss1/+ flies).
Expression of two copies of paraL1699F.Scer\UAS.1-1 under the control of Scer\GAL4elav-C155 exacerbates the bang-sensitive phenotype of parabss1/+ females: the mean recovery time increases from 38 to 52 seconds and the seizure threshold decreases from 19.1 to 12.1V.
