Read the following statements : (i) When fungus reproduces sexually, two haploid hyphae of compatible mating types come together and fuse (ii) In some fungi the fusion of two haploid cells immediately results in diploid cell (iii) In fungi of class the Ascomycetes and Basidiomycetes, an intervening diakaryotic stage (n$$ $$+$$ n i. e., two nuclei per $$cell) occurs. (iv) The dikaryotic cell may show fusion of nuclei to form diploid cell (v) The fungi of class Ascomycetes and Basidiomycetes have aseptate hyphae How many of the above statements are correct?

Infinity Learn · Accepted Answer

Septate mycelium is found in ascomycetes and basidiomycetes.When a fungus reproduces sexually, two haploid hyphae of compatible mating types come together and fuse. In some fungi the fusion of two haploid cells immediately results in diploid cells (2n). However, in other fungi (ascomycetes$$ and $$basidiomycetes), an intervening dikaryotic stage (n$$ $$+$$ n, i.e., two nuclei per $$cell) occurs; such a condition is called a dikaryon and the phase is called dikaryophase of fungus. Later, the parental nuclei fuse and the cells become diploid.
