Fundamentals of Genetics: Dominant and Recessive Traits

The video explains Mendel's hypothesis on inheritance, where each trait is controlled by two genes, one from each parent. Dominant traits mask recessive ones, which can reappear in subsequent generations. The pea plant experiment demonstrates this, showing how tallness (dominant) masks shortness (recessive) in the first generation, but shortness reappears in the second generation. The video concludes with a question about the genetic makeup of short plants.
