The physical basis of Mendel's laws explained. 📌 Topics Covered: • Sutton's grasshopper observations (1902) • Boveri's sea urchin experiments • Parallelism: chromosomes ↔ Mendel's laws • Morgan's sex-linked inheritance as experimental proof • Significance for modern genetics ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Transcript with Timestamp 0:00 Introduction — Chromosomal Theory of Inheritance 0:49 Timeline: 1865 Mendel published → ignored; 1900 rediscovered; 1902 Sutton & Boveri 1:48 Why Mendel's work was unrecognised — 3 reasons 2:20 By 1902: microscopes available; chromosome structure understood 2:29 Sutton & Boveri re-interpreted Mendel in terms of chromosomes 2:58 Comparison 1 — Mendel: genes (factors) in pairs → Sutton/Boveri: genes on chromosomes (homologous pairs) 4:12 Comparison 2 — Mendel: alleles segregate at gamete formation → S/B: chromosomes separate during meiosis 5:34 Comparison 3 — Mendel: independent assortment → S/B: chromosomes assort independently 7:06 Illustration: chromosome A (with A/a) and chromosome B (with B/b) assort independently 8:07 Physical evidence = chromosomes gave Mendel's theory credibility 8:35 Chromosomes CARRY genes from generation to generation = chromosomal theory ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Amazon Brand Store at https://www.amazon.in/neelabakoretuto....
