Others have male and female parts on the same flower. Self-pollination does not result in genetic variation, and therefore the seed from this process is usually not viable or of quality. In some cases, the plant&#8217;s biochemical makeup can recognize pollen grains from its flower and abort the process in the event of self-pollination.
