Explain the mechanism of dikaryotisation |
| Answer» Basidiomycota are filamentous fungi composed of\xa0hyphae\xa0(except for basidiomycota-yeast; refer\xa0yeast\xa0for more information) and reproduce sexually via the formation of specialized club-shaped end\xa0cells\xa0called\xa0basidia\xa0that normally bear external\xa0meiospores(usually four). These specialized\xa0spores\xa0are called\xa0basidiospores. However, some Basidiomycota reproduce asexually in addition or exclusively. Basidiomycota that reproduce asexually (discussed below) can be recognized as members of this division by gross similarity to others, by the formation of a distinctive anatomical feature (the\xa0clamp connection\xa0- see below),\xa0cell wall\xa0components, and definitively by\xa0phylogeneticmolecular analysis of\xa0DNA sequence\xa0data. | |
