Pollen normally fertilizes the flower in which it borne. New genetic material which would produce non-uniform offspring is not introduced through normal pollination 3. Wheat cultivars are homozygous pure line cultivars.
Corn is wind-pollinated and lands on the silks of the same or different plant.
This is not the case with hybrid corn where different inbred lines are used as the maternal and paternal sources and pollination is controlled by removing the tassels of the female plants and seed is not harvested from the male plants. There are exceptions to these two methods of reproduction. In sexual reproduction by seeds - specialized reproductive cells called gametes are formed in a process known as gametogenesis. Fusion of the male and female gametes leads to the development of an embryo and eventually a seed. Flowering and seed production is energy intensive for the plant.
