Having two haploid nuclei in one cell. A dikaryotic phase occurs in the life cycle of fungi because there is a delay between cytoplasm fusion and fusion of the nuclei, so all cells of a growing mycelium are dikaryotic.
                                                            
                                                     
                        
                                                
                        
                        
                            A cell that contains two separate haploid nuclei (n+n) which is different from being haploid (n) or diploid (2n). Naturally seen in fungal heterokaryons. Dikaryosis is a significant genetic peculiarity of the fungi.
                                                            
                                                     
                        
                                                
                        
                        
                            Having two different and distinct nuclei per cell; found in the fungi. A dikaryotic individual is called a dikaryon.
