Understand the process of meiosis: it is a type of cell division that reduces the chromosome number by half, producing cells that are genetically distinct from the parent cell.
Recall that meiosis consists of two consecutive divisions: meiosis I and meiosis II, each with its own phases (prophase, metaphase, anaphase, telophase).
Recognize that the starting cell is diploid (2n), meaning it has two sets of chromosomes, one from each parent.
During meiosis I, homologous chromosomes separate, resulting in two haploid (n) cells, each with one set of chromosomes but still duplicated.
During meiosis II, the sister chromatids separate, producing a total of four haploid cells, each with a single set of chromosomes and genetically unique.
