[Combination of chromosome breaks during formation of complex rearrangements in Drosophila sperm].
A collection of rearrangements in the left and right arms of Drosophila autosome-2 was established with use of the "non-disjunction test". Rearrangements were induced by gamma-ray irradiation of mature sperm. The observed frequencies of rearrangement configurations for the 4-breaks rearrangements demonstrated that only spatially close breaks can reunite. Rearrangements configurations observed for the 3-breaks rearrangements support rather the classic hypothesis of rearrangement formation than the exchange hypothesis.
