Meiotic division is a specialized type of cell division that occurs in organisms that reproduce sexually. It results in the formation of gametes, which are the reproductive cells, such as sperm and eggs. During meiosis, a single cell undergoes two rounds of division, reducing the chromosome number by half, from diploid to haploid. This ensures that when fertilization occurs, the resulting zygote has the correct number of chromosomes.
The process of meiosis consists of two main stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes are separated, while in meiosis II, sister chromatids are separated. This division is crucial for genetic diversity, as it allows for the mixing of genetic material from both parents, leading to unique combinations in the offspring.
