Question

What does the dikaryotic phase that is seen in some fungal members mean?

• A. Two nuclei in a cell
• B. Two cells in a hypha
• C. Two hyphae in a mycelium
• D. Two gametes in a cell

Answer 1

The correct option is A Two nuclei in a cell

A dikaryotic phase is seen when there is plasmogamy (fusion of the cells) without the fusion of the nuclei. The cell is not diploid but it has two nuclei. This is seen in some members of the fungal kingdom such as the ascomycetes and basidiomycetes.
