Difference between Anaphase of Mitosis and Anaphase I of Meiosis:
| Anaphase of Mitosis | Anaphase I of Meiosis |
|---|---|
| Centromeres divide during this stage. | Centromeres do not divide during this stage. |
| Sister chromatids separate and move to opposite poles. | Homologous chromosomes separate and move to opposite poles. |
| Each separated chromatid becomes an independent daughter chromosome. | Each chromosome still consists of two sister chromatids. |
| The chromosome number of daughter cells remains same as parent cell. | The chromosome number is reduced to half (reduction division). |
| Occurs in somatic cells for growth and repair. | Occurs in germ cells during gamete formation. |
| No genetic variation is introduced. | Leads to genetic variation due to prior crossing over and independent assortment. |
Conclusion:
Anaphase of mitosis ensures equal distribution of genetic material, whereas anaphase I of meiosis results in reduction of chromosome number and contributes to genetic diversity.
The process of appearance of recombination nodules occurs at which sub stage of prophase I in meiosis?
