- K12 and L2 represent independent lines of tert/nbs1 mutants, whereas 69–1 and 69–2 are two independent tert mutants. ND applies to when no bridged anaphases were available and no FISH was performed. In tert/nbs1 anaphase bridges were detected from G3 on, in both lines; in the majority of fused anaphase bridges telomere signals were detected. Nevertheless, from generation G4, telomeric signals were no longer detected. Anaphase bridges in tert mutants started to occur from G5 in both lines, and in a prevailing manner the bridges bore telomere-specific signals.
