Sex Linkage in Genetics | Class 12 Biology Lecture 10 | Irtisam’s Biology Welcome to Irtisam’s Biology! 🧬 In this lecture, we will explore Sex Linkage, an important topic in genetics and inheritance. Learn how certain genes are located on sex chromosomes (X and Y chromosomes) and how these genes are inherited from one generation to another. This lecture explains sex-linked inheritance with the famous Drosophila (Fruit Fly) Experiment by Thomas Hunt Morgan, which provided important evidence supporting the Chromosomal Theory of Inheritance. 📚 Topics Covered in Lecture 10: ✅ Introduction to sex linkage ✅ Sex-linked genes and sex chromosomes ✅ X-linked inheritance ✅ Y-linked inheritance ✅ Thomas Hunt Morgan's Drosophila experiment ✅ White-eye mutation in Drosophila ✅ Inheritance of eye colour in fruit flies ✅ Reciprocal crosses ✅ Criss-cross inheritance ✅ Colour blindness as an example of X-linked inheritance ✅ Important genetic crosses and concepts 🎯 Why Watch This Lecture? Understand how sex-linked genes are inherited, learn the importance of Morgan's experiments, and strengthen your conceptual understanding of genetics for board examinations and MDCAT preparation. 📖 Perfect For: Class 12 Biology students Punjab Board students Federal Board (FBISE) students Intermediate Biology students in Pakistan MDCAT aspirants Students preparing for genetics MCQs and board exams 🧬 Important: Watch the complete lecture to understand the Drosophila experiment and solve conceptual questions related to sex-linked inheritance. 👍 Like this video if it helps you understand Biology. 💬 Comment your questions about sex linkage below. 🔔 Subscribe to Irtisam’s Biology for more Biology lectures, conceptual explanations, important MCQs, and exam preparation. 📌 Lecture: 10 📌 Class: 12 📌 Subject: Biology 📌 Topic: Sex Linkage 📌 Example: Drosophila Experiment #SexLinkage #Class12Biology #IrtisamsBiology #Drosophila #SexLinkedInheritance #Genetics #ChromosomalTheoryOfInheritance #FBISE #PunjabBoard #MDCAT
