उत्तर
Meiosis is known as "reductional division" due to the fact that it entails two cycles of division (meiosis I and meiosis II) that lead to a decrease in the number of chromosomes. The chromosome number is effectively reduced by half during meiosis I, as homologous chromosomes are separated into distinct daughter cells. The haploid progeny cells generated during meiosis I are further divided during meiosis II. This process of reducing the chromosome number is essential for the maintenance of the diploid number in the zygote and the generation of genetic diversity.
