An individual or hermaphroditic organism is one that presents both reproductive sexual organs and / or is capable of generating both types of gametes (female or male sex cells). This genus is much more common to observe in plants; those with angiosperm flowers. These can have male organs (Androceo), female organs (gynoecium) and even both (hermaphrodite).
