Principles of Inheritance Part 3 | Dihybrid Cross, LOIA, Polygenic Inheritance | NEET Bio Genetics

Welcome to Principles of Inheritance & Variation – Part 3 (1-Hour Deep Dive Series)! Visit my Telegram channel for How to crack the NEET exam and free resource- https://t.me/biology300plus_by_manpre... In this lecture, we explore some of the MOST important Genetics concepts tested in NEET Biology, including: 👉 Incomplete Dominance (Pea seed size – NCERT) 👉 Dihybrid Cross 👉 Gregor Mendel’s Law of Independent Assortment (LOIA) 👉 Polygenic Inheritance (multi-gene traits) This session gives complete conceptual mastery with NCERT logic, Punnett squares, ratios, graphs and NEET-style reasoning. 🧬 What You Will Learn in This 1-Hour Class: 🔹 Incomplete Dominance (Pea Seed Size – NCERT Special Case) • What makes pea seed size a non-classical trait • Phenotypic ratio logic • Why it's incomplete dominance • NEET-level MCQ traps 🔹 Dihybrid Cross (NCERT Standard) • TTYY × ttyy • F1 hybrid formation • F2 phenotype ratio = 9:3:3:1 • Gamete formation logic • Punnett square (4 × 4) explained slowly • Why dihybrid cross proves LOIA 🔹 Law of Independent Assortment • What “assort independently” actually means • When LOIA works, when it fails • Chromosomal basis of assortment • NEET conceptual traps • Testcross 1:1:1:1 logic 🔹 Polygenic Inheritance (High NEET Weightage) • Multiple genes controlling single trait • Skin colour example • Continuous variation • Bell-shaped curve logic • Why polygenic ≠ multiple allelism • Why polygenic ≠ pleiotropy • MCQ patterns NEET loves 🔥 Additional Value: • NCERT line-by-line clarity • Easy memory tricks • Most expected NEET questions • Concept maps #neet2026 #neetcoachings #neetbiology #neetgenetics #principlesofinheritance #polygenicinheritance #dihybridcross #mendaliangenetics #incompletedominance
