1.The centromere of every chromosome divides.
2. Separation of sister chromatids takes place.
3. Only one chromatid of every chromosome moves to the pole (now called daughter chromosome).
4. The chromatids moving to one pole are genetically identical to those moving to the opposite pole (Before separation, these are sister chromatids held at a common centromere).
1.The centromere do not divide.
2. Homologous chromosome are separated.
3. Each homologous pair of chromosomes moves to the pole with both the chromatids.
4. The chromosomes moving to one pole are not genetically identical to those moving to the opposite pole.
