Respuesta :

Answer:

Sister chromatids separate during anaphase:  Mitosis, Meiosis II

Homologous chromosomes pair up and align at the metaphase plate: Meiosis I

Explanation:

After the S phase, each chromosome has two sister chromatids held together at the centromere. Splitting of centromere during anaphase of mitosis and anaphase-II of meiosis II is followed by separation of sister chromatids and their segregation towards the opposite poles of the cell.

Meiosis I is different from mitosis and meiosis II as it has many unique events that do not occur in the latter two. Prophase-I of meiosis I have many sub-stages. Zygotene of prophase I include the pairing of the homologous chromosomes to allow crossing over during pachytene. The paired homologous chromosomes align themselves at the cell's equator during metaphase I of meiosis I. This allows segregation of homologous chromosomes to the opposite poles in the subsequent stage.
