Verified step by step guidance1
Understand the process of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of haploid cells from a diploid parent cell. It is essential for sexual reproduction.
Recall the stages of meiosis: Meiosis consists of two consecutive divisions, meiosis I and meiosis II. Each division has its own phases: prophase, metaphase, anaphase, and telophase.
Focus on the outcome of meiosis I: During meiosis I, homologous chromosomes are separated, resulting in two haploid cells. However, these cells still contain duplicated chromosomes (sister chromatids).
Focus on the outcome of meiosis II: In meiosis II, the sister chromatids are separated, leading to the formation of four haploid daughter cells. Each of these cells has half the number of chromosomes as the original diploid cell.
Conclude that meiosis results in four haploid daughter cells, which are genetically distinct due to processes like crossing over and independent assortment during meiosis I.
