Summary

Two possible mechanisms are considered for the occurrence of experimentally or genetically induced duplications of bristles: extra cell division of a bristle mother cell versus determination of more than one mother cell. From a clonal analysis it appears that duplications induced by actinomycin-D arise by the latter mechanism, whereas those found in the mutantspl seem to arise by the former mechanism.
