Mucor

Vedclass · Answer

(A) In fungi,the sexual cycle involves three steps: plasmogamy,karyogamy,and meiosis.In lower fungi like Phycomycetes (e.g.,$Mucor$,$Rhizopus$),plasmogamy is immediately followed by karyogamy,leading to the formation of a diploid zygote $(2n)$.In higher fungi like Ascomycetes (e.g.,$Aspergillus$) and Basidiomycetes (e.g.,$Ustilago$,$Puccinia$),there is an intervening dikaryotic stage $(n+n)$ between plasmogamy and karyogamy,known as the dikaryophase.Therefore,$Mucor$ is the correct answer as it belongs to the class Phycomycetes where the dikaryotic stage is absent.

In which of the following is plasmogamy followed by karyogamy immediately?
