Cs2 - seed taste evol in peas (l4) The natural history of round and wrinkled peas. 12:00 pm: pisum sativum, common names: field peas, nati(cid:448)e to: nea(cid:396) east i(cid:396)a(cid:395), tu(cid:396)key, is(cid:396)ael, palesti(cid:374)e, habitat: agricultural and steppe fields, a key crop of the neolithic agricultural revolution, oldest recorded samples date to 10 000 bce. Traits selected during domestication: non-dehiscent pods, seeds stay protected within pods longer. Smooth seed coat: as opposed to a rough seed coat, smooth coats are harder to remove from the seed, this gives them more protection when stored. Larger seed size: higher volume of food, wrinkled seed shape, wrinkled peas are sweeter than round peas. The cell bio of round and wrinkled peas: wrinkled peas have two traits that differentiate them from round peas, seed shape. Round vs wrinkled: seed taste, wrinkled pees are sweeter. From mendel to molecules: gregor mendel the father of modern genetics. Inheritance of traits in pea plants (p. sativum).
