Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells from one diploid cell. It consists of two stages: meiosis I and meiosis II.
Recall that meiosis I separates homologous chromosomes, resulting in two cells, each with half the number of chromosomes as the original diploid cell. These cells are haploid.
Meiosis II is similar to mitosis, where the sister chromatids are separated. This division results in four cells, each containing half the number of chromosomes as the original diploid cell.
Each of the four cells formed at the end of meiosis II is haploid, meaning they contain one set of chromosomes. If the original cell was diploid with 2n chromosomes, each resulting cell will have n chromosomes.
Therefore, the correct answer is that meiosis II results in four cells, each with half the number of chromosomes as the original cell.
