Haplophase

Karyogamy

Dikaryophase

Syngamy

Text Solution

Verified by Experts

The correct Answer is:

In the certain classes of fungi such as Asecomycetes and Basi - diomycetes , as a result of plasmogamy (fusion of the protoplasm of two compatible gametes) the nuclei of the oppsite strains get themselves arranged in pairs but do not fuse. This phase in the life cycle is termed as dikaryophase and the process is called dikaryotization .
