Partial excision of the P{PZ} element, with 38bp of the P{PZ} sequences remaining. These sequences include two 15bp inverted repeats (that are vestiges of the 31bp inverted repeats of the parental P{PZ} element) and the 8bp target site duplication that accompanied the insertion of the parental P{PZ} element.
put10/put10460 adults are fully viable at 25oC, but show defects in wing venation in 28% of cases. put10 also produces viable adults in transheterozygous combination with put62, put51, put135 and put88, with the flies produced sometimes showing wing vein defects. Homozygotes are fully viable at 25oC, but show a semi-lethal phenotype at 18oC. Homozygotes do not show wing defects.
Precise excision of the P-element sequences in put10 is associated with reversion of the cold-sensitive lethality. Three classes of put allele can be identified with respect to decreasing severity of wing venation phenotypes with put10 : Class I (put10460 = put62) > Class II (put51 = put88 = put135) > Class III (put10 = put24 = put97).
