Distribution of IM-9 cells with adjacent chromosomes during mitosis. (A) Proximities between chromosomes 15 and 17 versus chromosomes 11 and 17: P < .05 in metaphase and anaphase. (B) Proximities between chromosomes 9 and 22 versus chromosomes 9 and 11:P < .05 in metaphase and telophase. The legends are as in Fig 2.
