Gene interaction is an important topic in NEET Biology. This NCERT-focused guide explains epistasis, pleiotropy and polygenic inheritance in a simple and exam-oriented way. It includes important examples, comparison tables, mnemonics and practice MCQs to help students prepare for NEET Biology 2027 . Study Note: Use this article together with the prescribed NCERT Biology textbook. For best results, understand the concept first and then practise questions. Quick Answer: Gene Interaction Gene interaction occurs when the expression of one gene is influenced or modified by another gene or genes. Therefore, the expression of a trait may depend on interactions among several genes rather than on a single gene acting independently. Epistasis: One gene masks or modifies the expression of another gene. Pleiotropy: One gene affects multiple traits. Polygenic inheritance: Multiple genes contribute to one trait. In This Guide What is Gene Interac...
