AIIMS 2017 Botany Reproduction in Fungi MCQ Question

Dikaryotisation (n + n) in Agaricus occurs through somatogamy, where two compatible hyphae from different strains fuse, leading to the formation of a dikaryotic mycelium. Clamp connections are structures that facilitate the maintenance of the dikaryotic state during cell division, thus both processes are integral to dikaryotisation, making option C correct. Option A alone does not account for the initial fusion of hyphae, while option D, basidiospores, refers to the reproductive spores produced after meiosis, not the dikaryotic stage. Understanding these processes highlights the complexity of fungal reproduction and development.
