Verified step by step guidance

Understand the process of meiosis, which consists of two consecutive divisions: Meiosis I and Meiosis II. Each division has several stages: Prophase, Metaphase, Anaphase, and Telophase.

Recognize that Meiosis I is the reductional division where homologous chromosomes are separated, resulting in two haploid cells. Meiosis II is similar to mitosis, where sister chromatids are separated.

Identify the stages of Meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I. During Prophase I, homologous chromosomes pair up and exchange genetic material. In Metaphase I, these pairs align at the cell's equator. Anaphase I involves the separation of homologous chromosomes to opposite poles.

Focus on Telophase I, where the separated homologous chromosomes reach the poles of the cell. This stage is followed by cytokinesis, which divides the cytoplasm, resulting in two haploid nuclei, each with half the original number of chromosomes.

Conclude that Telophase I is the stage in meiosis that results in two haploid nuclei, as it completes the first meiotic division and prepares the cells for Meiosis II.
