How Meiosis Drives Genetic Diversity: A Simple Guide
Outline: Understanding Meiosis and Its Role in Genetic Diversity Discover the stages of meiosis, the importance of genetic variation, and how this unique cell division process contributes to evolution and biodiversity. Introduction Brief introduction to cell division, focusing on meiosis as a key process in sexual reproduction. Importance of meiosis in creating unique offspring and contributing to genetic diversity. Contrast with mitosis, which occurs in regular body cells. 1. What is Meiosis? Definition of meiosis: a type of cell division that reduces the chromosome number by half, resulting in four genetically distinct cells. Purpose: formation of reproductive cells (sperm and egg). Importance in sexual reproduction and species survival. 2. Mitosis vs. Meiosis: Key Differences Mitosis: Occurs in somatic (body) cells, produces two identical daughter cells. Maintains the chromosome number (46 chromosomes in humans). Meiosis: Occurs in reproductive organs, produces four unique cells. Re...
