Abstract: | Summary We report a detailed molecular analysis of three chromosomal rearrangements, which have been produced during I-R hybrid dysgenesis in Drosophila melanogaster. They all disrupt the yellow gene. One of them is a deletion; the other two are inversions, which may be interpreted as the results of recombination events between I elements inserted at their break points. These events appear to occur at the time of transposition and involve integrating rather than resident I elements. They are produced by a mechanism very similar to homologous ectopic recombination. |
