Lecture : 32 🔥 দুই সাদা ফুল থেকে বেগুনি ফুল! Complementary Gene Interaction (9:7 Ratio)

🌸 How do two white flowers produce purple flowers? Unbelievable, but there is a scientific explanation in genetics! In this class, we will learn the famous Complementary Gene Interaction of Sweet Pea, where the ratio of 9:7 is found in the F₂ generation. 📌 What is included in this class: ✅ What is Complementary Gene Interaction? ✅ Why do two white flowers produce purple F₁? ✅ Simple explanation of the ratio of 9:7 ✅ Punnett Square Analysis ✅ Important MCQ and CQ tips for HSC, Admission and Board Exams Watch the video till the end to understand the difficult chapter of genetics in simple language and share it with your friends. 🔔 Subscribe to the channel to get more Biology and Genetics classes. A Sweet Pea plant with white male flowers will be shown, whose genotype is AAbb. A Sweet Pea plant with white female flowers will be shown, whose genotype is aaBB. There will be a cross (×) sign between both the plants. Below is a purple flower with a stem in the F₁ generation, with genotype AaBb. Next to it is a Punnett-square or genetic scheme that shows: A_B_ → purple flower (9) A_bb + aaB_ + aabb → white flower (7) Title: “Complementary Gene Interaction in Sweet Pea (9:7 Ratio)” Clear, colorful, textbook-style biology diagram. Genetic explanation The presence of both dominant genes—A and B—is required for the purple color to occur in sweet peas. A_B_ → Purple flower A_bb → White flower aaB_ → White flower ccpp → White flower Therefore, P: AAbb (White) × aaBB (White) F₁: All AaBb (Purple) F₂: AaBb × AaBb Result: 9 A_B_ = Purple 3 A_bb = White 3 aaB_ = White 1 aabb = White That is 9 Purple : 7 White, which is known as Complementary Gene Interaction.

Give its genetic explanation. Write a strong description box on this on YouTube class. I can't show the image directly here, but you can create an educational diagram using the prompt below: Image Layout Left: Sweet pea plant with white male flowers (Genotype: AAbb) Right: Sweet pea plant with white female flowers (Genotype: aaBB) Middle: Cross (×) Bottom F₁: Sweet pea plant with purple flowers (Genotype: AaBb) Further down F₂ ratio: 9 Purple : 7 White Educational, colorful, Biology textbook style Genetic explanation The two dominant genes A and B must be present together to produce purple pigment in sweet peas. P Generation: AAbb (white) × aaBB (white) Gamete: Ab × aB F₁: AaBb = all purple flowers F₂ (AaBb × AaBb): 9 A_B_ = purple 3 A_bb = white 3 aaB_ = white 1 aabb = white Therefore, 9 purple : 7 white This is Complementary Gene Interaction. #Genetics #biology #SweetPea #ComplementaryGeneInteraction #geneinteraction #biologyclass #hscbiology #admissionbiology #mendeliangenetics #scienceeducation #RadiumScienceAcademy
