In angiosperms, sex determination results in the formation of separate male and female flowers on either the same (monoecy) or different individuals (dioecy). Andromonoecy, where plants carry both male and perfect bisexual flowers, has evolved independently numerous times and is found in ~ 4,000 species in 33 angiosperm families. Several species in the Cucurbitaceae, including cucumber (Cucumis sativus) and melon (Cucumis melo), have bisexual floral primordia but often have flowers limited to a single sex. Sex determination occurs by the selective arrest of either the male stamen or female carpel during development.

在被子植物（angiosperms）中，性别决定过程会促使单性雄花与雌花的形成，这些花可着生于同一植株（单性同株，monoecy）或不同个体（单性异株，dioecy）上。雄花两性花同株（Andromonoecy）指植株同时着生雄花与完全两性花，该性状已独立演化多次，目前已在33个被子植物科的约4000个物种中被发现。葫芦科（Cucurbitaceae）的多个物种，包括黄瓜（Cucumis sativus）与甜瓜（Cucumis melo），虽具备两性花原基，但最终通常仅发育为单性花。其性别决定过程通过在花发育阶段选择性阻滞雄性雄蕊或雌性心皮的发育得以实现。
