Meiosis and Sexual Life Cycles — Genetic Variation, Crossing Over, and Chromosome Reduction Explained | Chapter 13 of Campbell Biology
Meiosis and Sexual Life Cycles — Genetic Variation, Crossing Over, and Chromosome Reduction Explained | Chapter 13 of Campbell Biology Welcome to Last Minute Lecture! This post explores meiosis and sexual life cycles—key processes that ensure genetic diversity and stability from generation to generation—as explained in Chapter 13 of Campbell Biology . Learn how meiosis reduces chromosome number, enables unique offspring, and drives evolutionary adaptability. Watch the full video summary below and subscribe for clear, chapter-by-chapter biology guides! Introduction: Why Meiosis Matters Meiosis is the process by which gametes (sperm and eggs) are formed, reducing chromosome number by half and generating genetic diversity through recombination and independent assortment. This diversity underpins evolution and the adaptability of sexually reproducing species. Asexual vs. Sexual Reproduction Asexual Reproduction: A single parent produces offspring that are genetically ide...
