What is the ploidy level of the cells in meiosis II?

During meiosis II, the cells are at the haploid stage. This is because meiosis consists of two consecutive divisions: meiosis I and meiosis II. In meiosis I, homologous chromosomes are separated, leading to the production of two haploid cells from one diploid parent cell. These haploid cells then undergo meiosis II, which is similar to mitosis, where the sister chromatids are separated. Therefore, the result of meiosis II is the formation of four haploid gametes.

This process is essential for sexual reproduction, as it ensures that each gamete carries half the genetic material necessary for forming a new organism when fertilization occurs. The ploidy level being haploid is key in maintaining the correct chromosome number across generations. After fertilization, the diploid state is restored in the zygote, but during meiosis II, the cells remain haploid throughout the division process.
