We explore Genetic Linkage and Crossing Over through the lens of Thomas Hunt Morgan’s groundbreaking research on fruit flies (Drosophila melanogaster). What You’ll Learn: Linkage vs. Independent Assortment: Why genes on the same chromosome don't always follow Mendel’s 9:3:3:1 ratio. The Drosophila Model: Why Morgan chose fruit flies (short life cycle, distinct traits, and clear sex differences). The "Aha!" Moment: Understanding why the F2 generation showed 62.8% parental types and 37.2% recombinants. Recombination Frequency: How the distance between genes determines the strength of their linkage. Key Genetic Concepts Covered: Complete Linkage: When genes are so close they never separate (e.g., male Drosophila). Incomplete Linkage: When crossing over occurs, creating new "recombinant" combinations. Gene Mapping: How Morgan's student, Alfred Sturtevant, used these percentages to create the first-ever chromosome maps. #Genetics #Biology #Drosophila #Linkage #CrossingOver #Morgan #NEETBiology #Class12Biology #ScienceExplained    / @sreekalasree123   This video is for educational purposes only and contains no copyright content.
