A
ascomycetes and basidiomycetes
B
phycomycetes and basidiomycetes
C
ascomycetes and phycomycetes
D
phycomycetes and zygomycetes
Answer
ascomycetes and basidiomycetes
Explanation
Solution
In fungi (ascomycetes and basidiomycetes), kayrogamy is delayed and occurs just before meiosis. In the stage intervening between plasmogamy and karyogamy the cells often contain two nuclei or dikaryons (n + n). Such cells are called dikaryotic cells. The phase is known as dikaryophase.
