(a) Define the following terms with an example (i) Hologamy (ii) Isogamy (ii) Anisogamy (iv) Merogamy (v) Paedogamy

Explanation

(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.
