Question

Some fungi exhibit a condition wherein they have two haploid nuclei (n+n) conditions after plasmogamy. This condition is called:

• A. metaphase
• B. synkaryon phase
• C. dikaryophase
• D. prophase

Answer 1

The correct option is C dikaryophase

Dikaryophase or dikaryon is where 2 cells with haploid nuclei fuse their cytoplasms such that there is just 1 cell with 2 distinct unfused nuclei. This is seen among some members of the fungal group especially the Basidiomycetes.

Synkaryon phase is the phase where 2 nuclei fuse together to form a single nucleus.

Metaphase is the second phase in mitosis and meiosis where the chromosomes arrange themselves along the equatorial plane.

Prophase is the first phase of mitosis and meiosis.
