- Plural of anisogamy; forms of sexual reproduction in which the two gametes (sex cells) differ in size, structure, or behavior.
Usage: biology; technical
Examples
- Many algae species exhibit anisogamies, where one gamete is larger and less mobile than the other.
- In anisogamies, the smaller gamete typically swims toward the larger, stationary one.
- Biologists study anisogamies to understand the evolution of sexual reproduction.
- The transition from isogamy to anisogamies represents an important step in reproductive specialization.
