Incomplete Dominance — one of the most tested exceptions to Mendel's Law of Dominance. 📌 Topics Covered: • What is Incomplete Dominance? • Antirrhinum (Snapdragon) flower colour example • 1:2:1 ratio in F2 (not 3:1) • Phenotype blends without genotype blending • NEET MCQ tips and PYQ patterns Transcript and Timestamp 0:00 Introduction — Variations from Mendel's principles 0:33 Concept of Locus — position of gene on chromosome 1:15 Intraallellic interaction vs Intergenic interaction 3:04 Types: Incomplete dominance & Co-dominance (intraallellic); Polygenic & Epistasis (intergenic) 4:17 Incomplete Dominance — definition 5:06 3 Examples: Mirabilis jalapa, Antirrhinum (Snapdragon), Andalusian fowl 6:06 Cross: Pure Red × Pure White → F1 all Pink 8:08 F2 phenotype ratio: 1 Red : 2 Pink : 1 White (1:2:1) 9:42 F2 genotype ratio: 1:2:1 10:18 Key: In incomplete dominance phenotype ratio = genotype ratio in F2 10:55 Compare with Mendelian: phenotype 3:1 vs genotype 1:2:1 11:41 Andalusian Fowl: Black × White → F1 Blue → F2 1:2:1 15:33 Farmer story — blue fowl sells at high price → bred blue × blue → only 50% blue!
