A dikaryotic cell has

Options

A. Two haploid nuclei
B. Diploid zygotes
C. Two similar nuclei
D. Two dissimilar haploid nuclei.

Answer

To answer the question "A dikaryotic cell has," we need to understand the definition and characteristics of a dikaryotic cell in the context of fungi.

### Step-by-Step Solution:

1. **Understanding Dikaryotic Cells**:
- A dikaryotic cell is formed when two fungal hyphae (filaments) undergo plasmogamy, which is the fusion of their cytoplasm, but not their nuclei.

2. **Nuclear Composition**:
- In a dikaryotic cell, there are two nuclei present. However, these nuclei are not fused; they remain separate within the same cell.

3. **Nature of the Nuclei**:
- Each of these nuclei is haploid, meaning they each contain one set of chromosomes. Since they come from two different parent fungi, they are genetically distinct but similar in that they are both haploid.

4. **Conclusion**:
- Therefore, a dikaryotic cell has two haploid nuclei, one from each parent fungus.

5. **Final Answer**:
- The correct option is: **two haploid nuclei**.
