Fig. 6. Graph showing the distribution of different types of
sex-chromosome/microtubule associations at different stages of division. We
scored 29 sex chromosomes in early prometaphase (EP), 14 sex chromosomes in
mid prometaphase (MP), 25 sex chromosomes in late prometaphase (LP), 20 sex
chromosomes in metaphase (M) and 26 sex chromosomes in anaphase (A). (When the
number of chromosomes is uneven, one sex chromosome in the group could not be
analysed.)
