Esterase 8 (E8) was mapped relative to d and cl using a slow allele obtained from M. Goodman (KN E8-S). The d cl; Clm4 stock used for this analysis carried a faster allele (E8-F), whose exact identity is unknown. Preliminary results indicate that E8 is located at the distal end of 3S, about 30 map units from d (Table 1). This puts E8 in the vicinity of g2 (R. Whalen, pers. communication), so the relative position of these 2 markers will now have to be determined.
