Nondisjunction
The diagrams that follow show nondisjunction during mitosis, meiosis I and meiosis II in a species that has a diploid chromosome number of 8.
Nondisjunction during Mitosis
![]() | Prophase |
![]() | Metaphase |
![]() | Anaphase |
![]() | Telophase Notice that the cell forming on the left has an extra chromosome and the cell forming on the right has a chromosome missing. |
![]() | G1 Interphase During this phase, the chromosomes uncoiled and not visible. |
![]() | G2 Interphase During this phase, the chromosomes uncoiled and not visible. |
