Meiosis is referred to as reduction division because it reduces the number of chromosomes by half. Here's a step-by-step explanation:

1. Meiosis begins with a diploid cell, which contains two copies of each chromosome, one from each parent. This cell undergoes DNA replication, resulting in duplicate copies of each chromosome.

2. The cell then undergoes two rounds of cell division, called Meiosis I and Meiosis II.

3. In Meiosis I, the homologous chromosomes (the two copies of each chromosome that were replicated) are separated. This results in two cells, each with a single set of chromosomes. However, each chromosome still consists of two sister chromatids.

4. In Meiosis II, the sister chromatids are separated. This results in four cells, each with a single set of chromosomes.

5. Therefore, the original diploid cell (with two sets of chromosomes) has been reduced to four haploid cells (each with a single set of chromosomes).

This reduction in chromosome number is crucial for sexual reproduction, as it ensures that when an egg and sperm combine at fertilization, the resulting offspring will have the correct number of chromosomes.
