Meiosis II Mind Map for NEET Biology | Step-by-Step Revision Notes   Simple mind map of Meiosis II showing all stages from Prophase II to formation of 4 haploid cells. - Dr.Sanjaykumar Pawar  🌿 MEIOSIS II (Second Meiotic Division) 👉 Meiosis II starts immediately after Meiosis I , without long gap. 👉 It is similar to mitosis (but produces haploid cells). 🔬 1. Prophase II Meiosis II begins just after cytokinesis of Meiosis I. Chromosomes may not fully elongate before starting again. Each cell is now haploid (n) . Chromosomes become short, thick, and visible again (condense). Nuclear membrane breaks down by end of prophase II. Spindle fibers start forming. 👉 Key point: ✔ Chromosomes re-condense ✔ Nuclear membrane disappears ✔ Spindle starts forming 📍 2. Metaphase II Chromosomes arrange themselves at the equator (middle line) of the cell. Each chromosome consists of two sister chromatids . Spindle fibers from opposite poles attach to kinetoch...
