Verified step by step guidance1
Recall that meiosis is a two-stage cell division process that reduces the chromosome number by half to produce gametes.
Understand that Meiosis I is the reductional division where homologous chromosomes are separated, resulting in cells with half the original chromosome number, which means the cells are haploid.
Recognize that Meiosis II is similar to mitosis, where sister chromatids are separated, but since the cells are already haploid, the chromosome number remains the same.
Determine the number of cells produced: Meiosis I results in two haploid cells, and Meiosis II divides each of these into two, resulting in four haploid cells total.
Conclude that the correct description is: Meiosis I produces two haploid cells, and Meiosis II produces four haploid cells.
