8 nucleotides at position 3726-4217 are deleted just overlapping the breakpoint of the E(spl)1 deletion (breakpoints 3730-4213), causing a frameshift.
Revertant of E(spl)m8-HLH1. An additional 4 bases are deleted on either side of the E(spl)m8-HLH1 breakpoints causing a frameshift.
Strong phenotypic reversion: 250--350 facets per eye. Viable when heterozygous with a Dl allele.
Revertant.
