Question

Dikaryon formation is characteristic of

• A. Ascomycetes and basidiomycetes
• B. Phycomycetes and basidiomycetes
• C. Ascomycetes and phycomycetes
• D. Phycomycetes and zygomycetes

Answer 1

The correct option is A Ascomycetes and basidiomycetes

In general, most of the fungi reproduce sexually and here the hyphae fuse allowing gamete nuclei to be transferred. But in the case of ascomycetes and basidomycetes, it is found that plasmogamy precedes karyogamy and resulting in formation of a dikaryon. This dikaryotic condition is unique to these fungi.
