Vedclass · Answer

(D) In the life cycle of Basidiomycetes,plasmogamy (fusion of protoplasm) occurs between two vegetative or somatic cells of different strains or genotypes. This results in the formation of a dikaryotic cell,where each cell contains two nuclei $(n+n)$ from different parents. These nuclei do not fuse immediately; instead,they divide independently along with the cell division,leading to the formation of a dikaryotic secondary mycelium. This prolonged dikaryotic phase is a characteristic feature of Basidiomycetes.
