[2] Andromonoecy is frequent among genera with zygomorphic flowers,[3] however it is overall rare and occurs in less than 2% of plant species.
Nonetheless the breeding system has gained interest among biologists in the study of sex expression.
[4] The word andromonoecious is a combination of andr- (meaning male) and monoecious and was first used in 1877.
[11] It has been suggested that andromonoecy evolved from hermaphroditism due to the loss of female structures.
[15] If female flowers are better at producing seeds than hermaphroditic ones, andromonoecy could evolve towards monoecy.
