Salient Features of Kingdom Fungi · NCERT Biology

In Ascomycetes and Basidiomycetes, an intervening stage occurs where a cell has two nuclei (n + n). This is called:

  1. Haplophase stage
  2. Diplophase stage
  3. Dikaryophase
  4. Polyploidy stage
Show answer and explanation

Correct answer: Dikaryophase

In higher fungi, plasmogamy is not immediately followed by karyogamy, leading to a dikaryotic stage (two nuclei per cell). This condition is known as the dikaryophase.
