Self-Pollination and Flower Anatomy

The video tutorial explains the concept of self-pollination, detailing the process, types, and adaptations that facilitate it. It also covers the genetic consequences, advantages, and disadvantages of self-pollination, and mechanisms that prevent it. The tutorial aims to provide a comprehensive understanding of how self-pollination works in plants, its benefits, and its limitations.
