Infinity Learn · Accepted Answer

In basidiomycetes, plasmogamy is brought about by fusion of two vegetative or somatic cells of different strains or genotypes of monokaryotic hyphae. The resultant structure is dikaryotic which ultimately gives rise to basidium. Karyogamy and meiosis take place in the basidium producing four basidiospores. The basidiospores are exogenously produced on the basidium.
