Verified step by step guidance

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

Recognize that Metaphase I is a phase within Meiosis I. During this phase, homologous chromosomes (each consisting of two sister chromatids) align at the metaphase plate, which is the equatorial plane of the cell.

Differentiate between homologous chromosomes and sister chromatids. Homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape and size. Sister chromatids are identical copies of a single chromosome, connected by a centromere.

Recall that the alignment of homologous chromosomes at the metaphase plate is crucial for the subsequent separation of these homologous pairs during Anaphase I, ensuring genetic diversity.

Note that the other options describe events that occur in different phases of meiosis or mitosis: Sister chromatids separate during Anaphase II of meiosis, the nuclear envelope re-forms during Telophase, and chromosomes condense during Prophase.
