Question:

An intervening dikaryotic stage occurs in-

Options:

1. Phycomycetes and Ascomycetes
2. Ascomycetes and Basidiomycetes
3. Basidiomycetes and Phycomycetes
4. Phycomycetes and Ascomycetes

Solution:

An intervening dikaryotic stage, also known as a "dikaryotic phase" or "dikaryotic stage," occurs during the sexual reproduction of fungi in the classes Ascomycetes and Basidiomycetes. In these classes, after the fusion of haploid cells (plasmogamy), the resulting structure is dikaryotic, meaning it has two distinct haploid nuclei without fusion (karyogamy) and formation of a diploid nucleus. This dikaryotic stage is a characteristic feature of sexual reproduction in Ascomycetes and Basidiomycetes.
