Question

write briefly about on parasexuality in fungi

Answer 1

Parasexuality in fungi can be called genetic recombination without meiosis. 
In the absence of meiosis during the life cycle of imperfect fungi, recombination of hereditary properties and genetic variation still occur by a mechanism called parasexuality.It includes the production of diploid nuclei in a heterokaryotic, haploid mycelium that results from plasmogamy and karyogamy; multiplication of the diploid along with haploid nuclei in the heterokaryotic mycelium; sorting out of a diploid homokaryon; segregation and recombination by crossing over at mitosis; and haploidization of the diploid nuclei. Sexual and parasexual cycles are not mutually exclusive. Some fungi that reproduce sexually also exhibit parasexuality. However imperfect fungi reproduce asexually and exhibit parasexuallity
