Genetics and Heredity Concepts

The video explores the pioneering work of Gregor Mendel, the father of genetics, who conducted experiments with pea plants to understand how traits are inherited. Mendel discovered hereditary units, now known as genes, which can be dominant or recessive. His work laid the foundation for modern genetics, although it wasn't recognized until after his death. The video also covers the historical context of Mendel's discoveries, including the later identification of chromosomes and the structure of DNA.
