      Reference

      Metaphases from Su(var)2-HP2Q2543X/Df(2R)B11 larval brains show a number of abnormalities (frequency of cells showing each phenotype is indicated in parentheses), such as abnormal chromosome condensation (0.5%), hyperploid/polyploid cells (1.0%), chromosome breaks (0.5%) and precocious sister-chromatid segregation (1.0%).
