The 13 complementation groups consist of four known groups (maoc-1, dhs-28, daf-22, and prx-10), which are separated from the nine new drop groups. Six screen series are defined according to the mutagen and background used. WT, N2 Bristol. Is[mddm], ssdIs1, and ssdIs5[maoc-1; dhs-28; daf-22; mrfp::pts1]. acs-22, a deletion allele acs-22(tm3236). Numbers of alleles are listed. ts, temperature-sensitive alleles; x, no mutant of the group expected due to Is[mddm] bypassing or acs-22 suppression; empty cell, no allele isolated.
