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
Journal of Heredity Journal of Heredity The Journal of Heredity is a peer-reviewed scientific journal concerned with heredity in a biological sense, covering all aspects of genetics. It is published by Oxford University Press on behalf of the American Genetic Association. The trends in topics that have been published in the journal reflect the history of the discipline of genetics. Early issues included many papers on eugenics, particularly under the editorial leadership of the journal's first two editors-in-chief, Paul Popenoe and R. C. Cook.
