A dikaryotic ascus that forms in the ascocarp undergoes karyogamy, meiosis, and mitosis to form eight ascospores. A diploid ascus that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A haploid zygote that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A dikaryotic ascus that forms in the ascocarp undergoes plasmogamy, meiosis, and mitosis to form eight ascospores.
- How is the life cycle of Ascomycetes different from that of humans? A. Haploid cells undergo meiosis. B. Haploid cells undergo mitosis. C. Diploid cells undergo meiosis. D. Diploid cells undergo mitosis. (photo attatched)Explain how a single haploid cell of Saccharomyces caneventually yield a diploid cell.When the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores.
