  • a Genotypes at the E(z) locus of males that were tested for P excisions from snw. These males were also heterozygous for the H(hsp/CP)2 transgene, which encodes the P transposase. Thus, the genotype of the tested males was (TP) snw; H(hsp/CP)2/+; E(z)28 or E(z)+/+.

  • b Average unweighted excision rate [(sn+ + sne)/(snw + sn+ + sne)] ± standard error.
