Answer 1

Self-Pollination

Self-pollination, or more exactly almost full self-pollination, is the principle mating system found in grain crops and in many vegetables. The majority of the 50–60 main grain crops of the world are predominantly self-pollinated. Only a few (such as maize, rye, pearl millet, buckwheat, or scarlet runner bean) are cross-pollinated. Now that the wild progenitors of the majority of the grain crops are already satisfactorily identified, we know that the wild ancestors of the self-pollinated crops are also self-pollinated. In other words, self-pollination in grain crops did not evolve under domestication.
