- Post-Copulatory Mechanisms
- Prolonged copulations - Mate Guarding
- Mating Plugs-Repellant
- Sperm Displacement
- Sperm Competition (number, size and characteristic)
- Arises through heterospermic insemination
- Based on Sperm Competition Theory and Raffle Principle
- High sperm competition environments and conditions = invest more in sperm production
- Characteristic - sperm head morphology e.g. hooked, big in drosophila.
- Bigger testes size when more competiton
- SIZE: Sperm length longer in high competition
- Number: SPERM PRUDENT ALLOCATION - MORE IN HIGH RISK
- Infantice
