Pea diminish leaf and stem growth. Adult weevils feed on the leaves and create a notched, "c-shaped" appearance on the outside of the leaves. In the mid-19th century, Austrian monk Gregor Mendel's observations of pea pods led to the principles of Mendelian genetics, the foundation of modern genetics. He ended up growing and examining about 28,000 pea plants in the course of his experiments. Mendel chose peas for his experiments because he could grow them easily, develop pure-bred strains, protect them from cross-pollination, and control their pollination. Mendel cross-bred tall and dwarf pea plants, green and yellow peas, purple and white
Adoption detective their parents is information that has been used since prehistoric times to improve crop plants and animals through selective breeding. The biological science of genetics, which began with the work of Gregor Mendel in the mid-nineteenth century, seeks to understand the process of inheritance and the physical basis for heredity in our DNA. What is known about human traits inherited through patients' families can save their lives—that is why gathering a person's complete and accurate medical family history is extremely important even as genetic medicine continues to explain more diseases. Many advances in biological medical science are anticipated in the
