Final answer:
Meiosis II is similar to mitosis, during which sister chromatids are separated, leading to the formation of haploid cells.
Step-by-step explanation:
The part of meiosis that is similar to mitosis is Meiosis II. In Meiosis II, similar to mitosis, sister chromatids separate, and the process includes familiar phases such as prophase, metaphase, anaphase, and telophase. This division results in the formation of four new genetically unique haploid cells. While Meiosis I involves the pairing and separation of homologous chromosomes, Meiosis II functions much like mitosis, dividing each chromosome's two sister chromatids into individual chromosomes to be allocated to different gametes.
