Mendelism (Gregor Mendel)

Mendelism is the scientific study of how traits are inherited from one generation to the next, based on the work of Gregor Mendel. He discovered that traits are controlled by units called genes, which come in pairs. Some genes are dominant, meaning they show traits even if only one copy is present, while others are recessive and only show if both copies are the same. Mendel's principles explain how traits pass through generations, leading to predictable patterns of inheritance, and laid the foundation for modern genetics.
