Recall that meiosis consists of two consecutive divisions: meiosis I and meiosis II, starting from one diploid parent cell.
Understand that meiosis I is a reductional division where homologous chromosomes separate, reducing the chromosome number from diploid (2n) to haploid (n).
Recognize that meiosis II is an equational division similar to mitosis, where sister chromatids separate, maintaining the haploid chromosome number.
Note that the end result of meiosis is four daughter cells, each with half the chromosome number of the original diploid cell, making them haploid.
Because of crossing over and independent assortment during meiosis I, these four haploid daughter cells are genetically distinct from each other and from the parent cell.
