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. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. 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.
