Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells from one diploid cell.
Recall that a diploid cell contains two sets of chromosomes, one from each parent. In humans, this is 46 chromosomes.
During meiosis, the cell undergoes two rounds of division: meiosis I and meiosis II.
In meiosis I, homologous chromosomes are separated, reducing the chromosome number by half. This is the key step where the chromosome number is halved.
In meiosis II, the sister chromatids are separated, similar to mitosis, but the chromosome number remains the same as after meiosis I, resulting in four haploid cells.
