Gregor Mendel Studied traits that occur in distinct forms. Developed true-breeding varieties When bred amongst themselves these plants produced offspring identical to the parent for that trait. Used mathematical analysis in his studies. Definitions Gametes: reproductive cells produced by sexually reproducing organisms. Two types: male gametes = sperm In plants: contained in pollen Female gametes = eggs In plants: contained in ovules which mature to seeds when fertilized Ovules contained in carpels Fertilization Fertilization: fusion of egg and sperm Self-fertilized: fusion of sperm and egg from same plant Cross fertilized: fusion of egg and sperm from two different plants Produced hybrids F1: first generation F2: second generation Mendel?s Model
