| 1706799742 | Aneuploidy zygote missing a chromosome is said to be a | Monosomic | 9 | |

| 1706828940 | Errors of meiosis or damaging agents such as radiation can cause breakage of a chromosome, which can lead to four types of chsnges in chromosome structure | Deletion, duplication, inversion, translocation | 13 | |
| 1706830455 | Occurs when a chromosomal fragment is lost | Deletion | 14 | |
| 1706836559 | A deleted fragment may become attached as an extra segment to a sister chromatid, producing a | Duplication | 15 | |
| 1706842784 | A chromosomal fragment may also reattach to the original chromosome but in reverse orientation, producing an | Inversion | 16 | |
| 1706845917 | The fragment joins a nonhomologus chromosome, a rearrangement called | Translocation | 17 | |

| 1706933970 | Translocation have been implicated in certain cancers, this disease occurs when a reciprocal translocation happens during mitosis of cells that will become white blood cells. In these cells, the exchange of a large portion of chromosme 22 with a small fragment of chromosome 9 produces a much shortened, easily recognized chromosome 22 called philadelphia chromosome.
