Trioecy
Presence of males, females, and hermaphrodites in a population
Trioecy , also spelled triecy , is a sexual system characterized by the coexistence of males , females , and hermaphrodites . It has been found in both plants and animals .[ 1] [ 2] Like androdioecy and gynodioecy , trioecy is a mixed mating systems .[ 3]
Terminology
Trioecy is also called tridioecy and subdioecy .[ 4]
The term trioecy comes from the Neo-Latin word Trioecia , a former order of trioecious plants.[ 5]
Evolution of trioecy
Trioecy may be an unstable transient state[ 6] associated with evolutionary transitioning from gynodioecy to dioecy .[ 7] [ 6] In brachiopod species, trioecy usually breaks into androdioecy or gynodioecy.[ 8] Other studies show that trioecious populations originated from gonochoristic ancestors which were invaded by a mutant selfing hermaphrodite, creating a trioecious population.[ 1] It has been suggested that chromosomal duplication plays an important part in the evolution of trioecy.[ 9]
But one study found that trioecy can be stable under nucleocytoplasmic sex determination .[ 10] Another theoretical analysis indicates that trioecy could be evolutionary stable in plant species if a large amount of pollinators vary geographically.[ 11]
Occurrence
Trioecy is a relatively common sexual system in plants,[ 12] estimated to occur in about 3.6% of flowering plant species,[ 10] although most reports of trioecy could be misinterpretations of gynodioecy .[ 13] It is rare as well as poorly understood in animals.[ 12]
Species that exhibit trioecy
The following species have been observed to exhibit a trioecious breeding system.
