Question

The two most closely related groups of fungi are the:
A) zygomycetes and chytrids.
B) basidiomycetes and ascomycetes.
C) basidiomycetes and zygomycetes.
D) ascomycetes and zygomycetes.

Accepted Answer

Basidiomycetes and ascomycetes are the most closely related groups of fungi based on genetic and morphological similarities. These two groups form a monophyletic clade known as the Dikarya, which is characterized by the presence of a dikaryotic stage in their life cycle (two nuclei per cell). The other two groups, zygomycetes and chytrids, are more distantly related and do not have a dikaryotic stage.
