Mendel's Genetics and Seed Color

The video tutorial explains Mendel's First Law of Genetics, also known as the Law of Segregation. It describes how Mendel conducted experiments with pea plants to understand how traits are passed from one generation to the next. The video details the setup of Mendel's experiments, the results showing the dominance of yellow seeds over green seeds, and the emergence of the concept of dominant and recessive genes. It concludes with Mendel's findings on the F2 generation, where a 3:1 ratio of yellow to green seeds was observed, reinforcing the idea of genetic segregation.
