Question : A dikaryon is formed when (A) Meiosis is arrested (B) the two haploid cells do not fuse immediately (C) cytoplasm does not fuse (D) None of the above

Answer»

MEIOSIS is arrested 
the two haploid cells do not fuse immediately 
cytoplasm does not fuse 
None of the above 

Solution :Dikaryon is a stage/PHASE of a CELL, in which, there are two nuclei. This condition arises, if fusion of cytoplasm (plasmogamy) is not immediately followed by fusion of nuclei (karyogamy). Karyogamy is delayed, it OCCURS just before meiosis. Dikaryon occurs in stage intervening between plasmogamy and karyogamy. Such cells are CALLED dikaryotic cells and the phase is called dikaryophase.
