Course Overview: Biotechnology and Genetic Engineering Explained
Meiosis is the specialized cell division process that produces gametes (sperm and egg cells) and drives genetic diversity in sexually reproducing organisms. This micro-course explains each stage of meiosis, how chromosomes behave, and how meiosis differs from mitosis. Across six short, visual concepts, you’ll see how chromosome number is halved, how DNA is shuffled through crossing over, and how mistakes like nondisjunction lead to genetic disorders.
