Examples

• Many flowering plants exhibit dioecisms, with some individuals producing only male flowers and others only female flowers.
• The dioecisms found in ginkgo trees mean that only female trees produce the fleshy, foul-smelling seeds.
• Botanists study dioecisms to understand reproductive strategies in plant populations.
• Dioecisms require cross-pollination between separate male and female plants for successful reproduction.
• The prevalence of dioecisms varies significantly across different plant families and species.
