Meiosis occurs in the reproductive mother cell of the organism. Germ cells have a diploid number of chromosomes. Meiosis is cell division
done in two steps. Meiosis-1 and Meiosis-II. In meiosis-1, each cell divides to produce two daughter cells. In this process, both the cell nucleus and the chromosomes divide. The chromosome number of the resulting daughter cell is half the chromosome number of the mother cell. Hence meiosis-1 is called reductive division. The sperm and egg produced in meiosis are haploid in nature. That is, the number of chromosomes in the resulting cell is halved. Hence meiosis is called reductive division.
