P{PZ} insertion in the intron between exons 8 and 9. The orientation of the P{PZ} element is such that the ry marker gene is towards the 5' side of the pum gene while the Ecol\lacZ gene is oriented towards the 3' side.
By the adult stage, all homozygous females have "differentiated ovaries" (containing recognisable egg chambers and/or germline cells in at least one ovariole).
pum07098 and pum06897 have identical P{PZ} insertion sites.
