Fig. 2.
Telomere fusion frequencies in various mutants. The graph depicts the average frequencies for different types of fusion and their sums, which are indicated by the numbers next to the horizontal bars with the number of nuclei scored in parentheses. Even though a double fusion is likely derived from the replication of a single G1 fusion, we cannot rule out that some double fusions were the result of independent fusions occurring in G2. We count each double fusion as two fusions for frequency calculations. Even with a double fusion counted as a single G1 event, our conclusions are fully supported by statistical analyses (data not shown). In the Genotype column, the common non-Drosophila nomenclatures are provided in parentheses. *, Data from ref. 7; **, data from ref. 23. LP, late pupal; EP, early pupal; L3, late larval; nd, not done.
