Linkage (com exercício) - Aula 15 - Módulo II: Genética | Prof. Gui

🧬 EXTENSIVE BIOLOGY COURSE: https://bit.ly/extensivobio 🚀 MASTERING THE ENEM (Brazilian National High School Exam): https://bit.ly/DoE2026 🎯 PLATFORM: https://bit.ly/plataformaGUI 🟢📣 MATERIAL HERE: https://bit.ly/BIOLOGIAprofGUI In this lesson, I explain linkage, also called gene linkage, showing how the behavior of linked genes is different from what occurs in the independent assortment proposed by Mendel's Second Law. We will understand how to identify parental and recombinant gametes, differentiate cis and trans configurations, and analyze why the distance between genes directly interferes with the recombination frequency. In addition, I solve an exercise to show how this content appears in the ENEM and university entrance exams. 00:00 Introduction and definition 01:07 How was it in independent assortment? 02:54 What is it like in linkage? 05:15 Parental and recombinant gametes 10:01 The first rule of linkage 11:11 Cis or Trans? 13:38 The distance between genes is crucial! 17:23 Solving an exercise #biology #enem #genetics
