What happens to the chromosome number during anaphase and telophase?

During the stages of anaphase and telophase in mitosis or meiosis:

1. Anaphase: In both mitosis and meiosis, anaphase is the stage where the sister chromatids or homologous chromosomes separate and move toward opposite poles of the cell. In anaphase I of meiosis, homologous chromosomes separate, while in anaphase II of meiosis and anaphase of mitosis, sister chromatids separate. As the chromatids or chromosomes move toward opposite poles, the chromosome number remains unchanged. Each pole receives a complete set of chromosomes.
2. Telophase: During telophase, which follows anaphase, the separated chromosomes or chromatids arrive at the poles of the cell. In telophase of mitosis or meiosis, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to decondense back into chromatin. At the end of telophase, the chromosome number remains the same as the original number of chromosomes present in the parent cell before the process began.
