Three Point Test Cross | Gene Mapping | Finding Middle Gene & Map Distance

🧬 Three Point Test Cross | Gene Mapping | Finding Middle Gene & Map Distance (Step-by-Step Explanation) In this video, I explain how to solve a three-point test cross problem using data from Drosophila melanogaster. You will learn: ✔ How to identify parental types ✔ How to detect double crossovers (DCO) ✔ How to find the middle gene ✔ How to calculate map distance (centiMorgan) ✔ How to draw the final genetic map 📊 Data Used in the Problem (Total = 1000): ABC – 350 abc – 340 Abc – 90 aBC – 80 ABc – 60 abC – 50 AbC – 15 aBc – 15 📌 Final Results Explained in the Video: Gene Order: A – B – C Distance A–B = 20 cM Distance B–C = 14 cM 🎯 This video is useful for: • Class 11 & 12 Biology • NEET preparation • BSc Genetics • Competitive exams • University practical exams 🔔 Don’t forget to: 👍 Like the video 📤 Share with your classmates 🧬 Subscribe for more Genetics & Biotechnology lectures #Genetics #ThreePointTestCross #GeneMapping #NEETBiology #BScGenetics #BiologyLecture   / @sreekalasree123   This video is for educational purposes only and contains no copyright content.
