Crossing over happens in the pachytene stage of prophase I, bhai, when homologous chromosomes pair up and exchange segments 🧬. Then, the two divisions: meiosis I separates those homologous pairs, and meiosis II separates the sister chromatids—that's how we go from diploid to haploid, yaar!
I remember this clearly from revising last night while stressing about my dad's loan EMIs, and the chapters felt as tangled as my worries. But just like Uncleji at my gym finally nailing that push-up, untangling this concept felt like a small win 💪.
