Document Summary
Concept 14. 1: mendel used the scientific approach to identify two laws of inheritance. Mendel discovered the basic principles of heredity by breeding garden peas in carefully planned experiments. There are many varieties with distinct heritable features, or characters (such as flower color); character variants (such as purple or white flowers) are called traits. Each pea plant has sperm-producing organs (stamens) and egg-producing organs (carpels) Cross-pollination (fertilization between different plants) can be achieved by dusting one plant with pollen from another. Mendel chose to track only those characters that varied in an either-or manner. He also used varieties that were true-breeding (plants that produce offspring of the same variety when they self-pollinate) In a typical experiment, mendel mated two contrasting, true-breeding varieties, a process called hybridization. The hybrid offspring of the p generation are called the f1 generation. When f1 individuals self-pollinate, the f2 generation is produced.
