Verified step by step guidance

Understand the process of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of four haploid cells from one diploid cell. It consists of two stages: Meiosis I and Meiosis II.
Review Meiosis I: During Meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over. This stage ends with the separation of homologous chromosomes into two cells, each with half the original number of chromosomes.
Examine Meiosis II: Meiosis II resembles mitosis, where the sister chromatids of each chromosome are separated into different cells. This stage does not involve pairing of homologous chromosomes or crossing over.
Identify the outcome of Meiosis II: At the end of Meiosis II, the result is the formation of four haploid cells, each containing one set of chromosomes. This is crucial for sexual reproduction, as it ensures genetic diversity.
Clarify the incorrect options: Pairing of homologous chromosomes and crossing over occur during Meiosis I, not Meiosis II. Chromosome replication occurs before meiosis begins, during the interphase.
