Understand that meiosis is a special type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid precursor.
Recall that meiosis consists of two main sequential divisions: meiosis I and meiosis II.
Recognize that meiosis I is the reductional division where homologous chromosomes separate, reducing the chromosome number from diploid to haploid.
Know that meiosis II is the equational division where sister chromatids separate, similar to mitosis, resulting in haploid daughter cells.
Conclude that the total number of sequential cell divisions in meiosis to produce haploid cells from a diploid precursor is two.
