  1. Three sequential FISH with chromosome-end specific probes revealed enhanced occurrence of 2R chromosome ends in line K12 of the tert/nbs1 double mutants. In the sibling line K2, the fusion points were represented by random chromosome-arm interactions. In tert mutants lines 69–1 and 69–2, the occurrence of anaphase bridges starts from G5 on. Although the number of anaphase bridges available for analyses was rather low, cf. Figure 3G, only in one case the 2R-2R fusion had been detected. ND - no anaphases available.
