ABSTRACT
Frequency of reversions to wild type varies for thi and its derivatives from 10(-2) to 10(-5). A broad spectrum of mutations arises in thi alleles and thi+ revertants. Among them there are r, w, Bd and new mutations causing scalloped wings with thickened veins in all the autosomes. In the offspring of a Cy/thi 1 male a fly is found carrying a thi 1 allele in the Cy chromosome; this is not caused by crossing-over, but probably by a transposition. Mutations in the thi, Bd strains and their derivatives are supposed to be caused by small insertion. The nature of these insertions are under discussion.
