Web21 sep. 2024 · For organisms to grow, cells divide and reproduce into two ways: Mitosis and Meiosis. Thus for a better understanding of cells, it is essential to understand Mitosis Vs. Meiosis. This post explores both kinds of cell division characteristics, shining a light on key similarities and differences between mitosis vs. meiosis. So, let’s read in brief. WebKey messages. Meiosis is a type of cell division by which gametes – eggs and sperm – are formed. It includes two rounds of cell division to produce four haploid cells from a single diploid cell. Several processes during meiosis ensure the genomic material is ‘mixed up’ to ensure the resulting zygote contains a unique genome.
