Definition

1. Adjective:
   • Having male and female reproductive organs in separate plants or animals: A biological term describing a species in which individual organisms are distinctly either male or female, each producing only one type of gamete (sperm or egg). This contrasts with monoecious or hermaphroditic species where a single individual has both types of reproductive organs.

Usage Examples

• Adjective:
  • Holly trees are dioecian; you need both a male and a female tree planted near each other to produce berries.
  • In dioecian animal species like most mammals, the male and female individuals are often morphologically distinct.

Advanced Usage

• Technical/Biological Context: The term is primarily used in formal scientific writing, botany, and zoology. It is a precise descriptor for reproductive strategies.
  • The study focused on the evolutionary advantages of dioecian plant populations over hermaphroditic ones.

Variants and Related Words

• Dioecism (n): The state or condition of being dioecious.
