Define the following terms with an example (i) Hologamy (ii) Isogamy

1.	Define the following terms with an example (i) Hologamy (ii) Isogamy (iii) Anisogamy (iv) Merogamy (v) Paedogamy
Answer» (i) Hologamy: In Hologamy, the adult individuals do not produce gametes, but they themselves act as gametes and fuse to form new individuals. E.g.: Trichonympha (ii) Isogamy : Fusion of morphologically and physiologically similar gametes. E.g.: Monocystis (iii) Anisogamy : Fusion of morphologically and physiologically dissimilar gametes. E.g.: Vertebrates. (iv) Merogamy : Fusion of small sized morphologically different gametes (merogametes) (v) Paedogamy : Fusion of young individuals produced immediately after the mitotic division of adult parent cell.
