| We have noticed that multiple clones carried an aberrant chromosome III that was indistinguishable by size. |
| Bone marrow cells exhibited chromosome aberrations, aneuploidy, and changes in the mitotic index. |
| Removal of this aberrant chromosome from further calculations makes no change to the inferences drawn. |
| Genetic factors such as parental chromosome abnormalities are a major known cause which should be looked for. |
| They are formed by acentric chromosome fragments or whole chromosomes which are not incorporated into daughter nuclei during cell division. |
| To allow comparison between sexes, X chromosome abnormalities were concurrently studied in women. |
