Verified step by step guidance1
Recall that meiosis consists of two sequential divisions: meiosis I and meiosis II, starting from one diploid parent cell.
Understand that meiosis I is a reductional division where homologous chromosomes separate, resulting in two haploid cells, each with duplicated chromosomes.
Recognize that meiosis II is an equational division similar to mitosis, where sister chromatids separate, producing four haploid daughter cells in total.
Note that each of the four daughter cells is genetically distinct due to crossing over and independent assortment during meiosis I.
Conclude that from one diploid parent cell, meiosis produces four haploid daughter cells, each genetically unique.
