Gametangial copulation(conjugation) is common in
In gametangial copulation two gametangia come in contact and fuse completely to form a zygote or zygospore. It is found in members of zygomycetes, e.g., Rhizopus and Mucor.
Dikaryon formation is characteristic of
Plasmogamy is fusion of
It is the first stage of sexual reproduction in which the cytoplasm of two sex cells fuse with each other. The nuclei of sex cells come close to each other but do not fuse. Thus the resulting cell becomes binucleate or dikaryon.
Clamp connection is found in
In many members of basidiomycetes cells division accompanied by clamp connection. These are bridge(hook) like connection. They function as bypass hyphae through which nuclei migrate to make all of mycelium dikaryotic.
