  • a Genotypes of the aubergine, homeless, or piwi locus in the 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; aub or piwi/H(hsp/CP)2; +/+ or (TP) snw; +/H(hsp/CP)2; hls/+. The aub and piwi mutations were maintained in stocks with the Cy Roi [= In(2L)CyLtR + In(2R)Cy, Cy Roi cn sp bw] balancer chromosome; the hls mutations were maintained in stocks with the TM6, Tb e balancer chromosome.

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