move together to form a tetrad and synapsis begins. This is where crossing over occurs resulting in the recombination of genes. Metaphase I moves the tetrads to the metaphase plate in the middle of the cell, and Anaphase I reduces the tetrads to their original two stranded form and moves them to opposite poles. Telophase I then prepare the cell for its second division. Meiosis II generally resembles mitosis except that the daughter cells are haploid instead of diploid. DNA replication does not occur in Interphase II, and prophase, metaphase, anaphase, and telophase occur as usual. The only change is the number of chromosomes. (Friedman, 2017) Questions 1. What three important properties differentiate meiosis and mitosis? Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells whereas meiosis produces haploid cells. Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells. Lastly, mitosis is involved in growth and cell repair while meiosis helps in creating diversity through sexual reproduction. (Wilgar et al., 2020) 2. Describe how you can differentiate the following dividing cells: (a) prophase I from prophase II, During prophase I , differences from mitosis begin to appear. As in mitosis, the chromosomes begin to condense, but in meiosis I, they also pair up. Each chromosome carefully aligns with its homologue partner so that the two matches up at corresponding positions along their full length. During
