Gene Interaction Part-2 | Duplicate, Complementary & Supplementary Gene Action | Genetics | GPB |

Welcome to Fundamentals of Genetics – Gene Interaction Part-2 by AgriScholars! 🌱 In this lecture, we will explore three important types of *gene interaction* and their characteristic F₂ phenotypic ratios, essential for Agriculture Entrance Examinations, ICAR PG/AIEEA, CUET PG, UPCATET, CSIR-NET and other competitive exams. 📚 *Topics Covered:* 1. *Duplicate Gene Action (15:1)* – How either of two dominant genes can produce the same phenotypic effect. 2. *Complementary Gene Action (9:7)* – How two dominant genes work together to express a particular phenotype. 3. *Supplementary Gene Action (9:3:4)* – How one gene modifies or supplements the expression of another gene. 🎯 *What You Will Learn:* Genetic basis of gene interactions. F₂ phenotypic ratios and their derivation. Differences among duplicate, complementary and supplementary gene action. Important concepts and exam-oriented points for competitive examinations. 🌾 *Useful for:* B.Sc. Agriculture, ICAR PG/AIEEA, UPCATET, UP College Agriculture Entrance, CUET PG, CSIR-NET and other agriculture and life science examinations. 📌 Subscribe to *AgriScholars* for more lectures on Genetics, Plant Breeding and Agriculture Entrance Preparation. 👍 Like, Share and Comment your doubts! #Genes #genetics #generalknowledge #complementary #supplementary #geneticsexplained #plantbreeding #icar #upcatet #csirnet
