SET 2: Mendel's
Laws of Inheritance - Monohybrid and Dihybrid Crosses
Introduction: This set
focuses on Gregor Mendel's pioneering experiments on pea plants, his laws of
inheritance, monohybrid and dihybrid crosses, and the concepts of dominant and
recessive traits. Understanding these principles is fundamental to genetics.
