    In(1)BM1/0 males are bb and variegate for pdf. Primary nondisjunction 0.4 and secondary 18.5%; recombination 32% in In(1)BM1/+ and 35.4% in In(1)BM1/+/Y female (Grell, 1962, Genetics 47: 1737-54). Males reared at 18o show diffuse polytene X. (Lakhotia and Mishra, 1983, Indian J. Exp. Biol. 20: 643-51).
