Solution

When two hyphae come together, they form a dikaryotic cell. Here's the step-by-step process:

  1. Plasmogamy: This is the first step where the cytoplasm of two parent mycelia fuse together. This does not immediately involve the nuclei.

  2. Dikaryotic Stage: After plasmogamy, the cell becomes dikaryotic - meaning it contains two genetically distinct nuclei in the same cell. This is the stage that occurs when two hyphae come together.

  3. Karyogamy: This is the final step where the two nuclei fuse together to form a diploid cell. This does not occur immediately after two hyphae come together, hence the correct answer to your question is a dikaryotic cell.

Please note that a zygote, a gamete, or a diploid cell are not formed immediately when two hyphae come together.
