Mutation resulting in a frame-shift from the 14th codon of L-PB followed by a premature stop codon.
ATGATCC
Sequences in L deleted and replaced with ATGATCC, causing a frameshift.
Selected as a revertant of the L2/+ eye phenotype; 40-80% of heterozygotes show a weak mutant eye phenotype, such as a small dent in the anterior part of the eye.
