Understand that meiosis is a special type of cell division that reduces the chromosome number by half to produce gametes or spores.
Recall that meiosis consists of two main stages: Meiosis I and Meiosis II, each involving a nuclear division.
In Meiosis I, homologous chromosomes are separated into two daughter nuclei, which is the first nuclear division.
In Meiosis II, the sister chromatids of each chromosome are separated into two new nuclei, which is the second nuclear division.
Therefore, the total number of nuclear divisions during meiosis is two.
