Verified step by step guidance

Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells. It consists of two stages: Meiosis I and Meiosis II.

Recall that Metaphase II is a stage in Meiosis II, which follows Meiosis I. During Meiosis I, homologous chromosomes are separated, while Meiosis II is similar to mitosis, where sister chromatids are separated.

In Metaphase II, the key event is the alignment of sister chromatids at the metaphase plate. This is similar to Metaphase in mitosis, where chromosomes line up at the cell's equatorial plane.

Differentiate between the events of Metaphase I and Metaphase II. In Metaphase I, homologous chromosomes align at the metaphase plate, whereas in Metaphase II, it is the sister chromatids that align.

Conclude that during Metaphase II of meiosis, the correct event observed is the alignment of sister chromatids at the metaphase plate, preparing them for separation in the subsequent Anaphase II.
