Androdioecy /ˌændroʊdaɪˈiːsi/ is a reproductive system characterized by the coexistence of males and hermaphrodites. Androdioecy is rare in comparison with the other major reproductive systems: dioecy, gynodioecy and hermaphroditism.[1] In animals, androdioecy has been considered a stepping stone in the transition from dioecy to hermaphroditism, and vice versa.[2]
Androdioecy, trioecy and gynodioecy are sometimes referred to as a mixed mating systems.[3] Androdioecy is a dimorphic sexual system in plants comparable with gynodioecy and dioecy.[4]
