Advantages of Self-pollination	Advantages of Cross-pollination
Parental characters are preserved indefinitely.	There are variations in character leading to production of new varieties.
It is much surer in bisexual flowers where stamens and carpels mature at the same time.	The seeds produced are abundant and viable.
