As in all macrofungi, there is the formation of sexual spores, which lead to a combination of genetic information from two parents. Two hypotheses have been put forth to explain the origin of the Basidiomycetes. Phylum Ascomycota is also called ascomycetes and it is considered as the largest phylum of the fungi kingdom with approx 64000 species. Ascomycetes mainly reproduce by budding and fission, yeasts also engage in sexual reproduction that results in the production of an ascus, which makes them classified under Ascomycota. Q.2.
