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. Based on the diagram, how many unique ascospores are produced in each ascus resulting from the cross fertilization of two Ascomycetes fungi?   A. 1 B. 2 C. 4 D. 8
