2bp deletion resulting in a frameshift at amino acid residue 45.
A 2 bp deletion that leads to a frameshift beginning in aa 47 of piwi.
decreased fecundity | female (with piwig2)
female sterile (with piwig2)
viable (with piwig2)
piwig1/piwig2 females develop gonads but are sterile, as they lay much fewer eggs than piwig1/+ controls and none of these develop into a larva.
