b. Anisogamy – Fusion of morphologically or physiologically dissimilar gametes (Example: Allomyces).
c. Oogamy – Fusion of both morphologically and physiologically dissimilar gametes. (Example: Monoblepharis) - Gametangial contact: During sexual reproduction, a contact is established between antheridium and Oogonium (Example: Albugo)
- Gametangial copulation: Fusion of gametangia to form zygospore (Example: Mucor, Rhizopus).
