Mechanism of Meiosis
Meiosis is a specialized form of cell division that reduces the chromosome number by half, creating four genetically diverse haploid cells from an original diploid cell. During Meiosis I, homologous chromosomes, each consisting of two sister chromatids, pair up in a process called synapsis and then cross over, where homologous chromosomes exchange genetic material, increasing genetic diversity. Then, these homologous chromosomes are pulled to opposite poles, reducing the chromosome number by half.
During meiosis II, the sister chromatids between the two daughter cells split, resulting in the formation of four additional haploid gametes. Meiosis II functions similarly to mitosis, with the exception that homologous chromosomes are only present in one set in each dividing cell.
Meiosis I – Reductional Cell Division
Meiosis I, often known as reductional cell division, reduces the chromosome number to half while promoting genetic diversity. Similar pairs of chromosomes split off and enter the two daughter cells during this phase. As a result, half of the entire number of chromosomes is obtained. Meiosis, a process in the life of sexually reproducing organisms, ensures genetic diversity and stable chromosome numbers across generations. In this article, we will read about What is Meiosis I, the mechanism of Meiosis I, the Phases of Meiosis I, the significance of Meiosis I, and Meiosis vs. Mitosis.
