Gregor Johann Mendel is known as the father of modern genetics. He used cross-breeding to develop different kinds of peas. This allowed him to make predictions about the outcomes. These are now called Mendel's Laws of Heredity. They explain how traits are passed from generation to generation. Mendel also discovered dominant and recessive genes.
British scientist Robert Hooke built an early microscope and was the first scientist to observe cells and give them their name.
