ND, not determined.

  • a All mcl lines gave fourth chromosome loss rates of ≥5% when scored in the initial assay; the percentages shown here are the average percentage of fourth chromosome loss based on three or more separate trials.

  • b Timing of chromosome loss as meiotic is based on the observation of micro- and/or macro-nuclei in onion-stage spermatids.

  • c For these lines, there was no cytological evidence for chromosome loss during spermatogenesis.
