A comprehensive scientific diagram illustrating the eukaryotic cell cycle and a direct comparison between mitosis and meiosis. The left panel shows a continuous loop of interphase (G1, S, G2 phases) leading to the M phase (mitosis). The right panel provides a side-by-side analysis of mitosis versus meiosis, detailing parent cell (2n) division, chromosome count changes, occurrence in somatic or germ cells, and function
