Twin-spot analysis confirms that hyper-recombination occurs through reciprocal exchange. (A) Position of mwh1 and flr3 markers relative to the centromere and CG7670 locus on chromosome 3 (not to scale). (B–F) Wing blade twin-spot mwh flr clones were analysed microscopically. mwh clones are outlined with red broken lines and flr clones by blue broken lines. (B, C) mwh-flr twin spots resulting from recombination proximal to flr (within interval (b) in diagram). (D–F) complex clones indicating sequential recombination events. Arrows in (E), (F) and the inset in (E) indicate a possible mwh flr double mutant cell.
