In(3LR)bxd106LHR33R is not strictly known to be the precursor to Dp(3;3)S2. Dp(3;3)S2 is stated to have been "synthesized via a sequence of selected single exchanges", starting from In(3LR)HR33 and In(3LR)bxd106, but the intermediates were not specified. To generate this chromosome from In(3LR)bxd106LHR33R, a crossover must have occurred between the two copies of 87B4--89E2, inverting the region 88ish - 61A | 87B - 88ish. Alternatively the crossover in that region could have occurred between the original inversions In(3LR)HR33 and In(3LR)bxd106, with the reciprocal recombinants then undergoing a second crossover event. However, In(3LR)bxd106LHR33R and Dp(3;3)S2 are interconvertable by meiotic recombination --at least on paper -- hencenthe listing of both arrangements in the same entry.
Dp(3;3)S2 is not mentioned specifically, but the method used for making this set of rearrangements is described here and evidently nowhere else.
Useful for selection of induced deficiencies and tandem duplication of segments in region 61A-72D
