- 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. Although ascospores are produced by mitotic division, none of the spores develop into fungi that are identical to either parental hyphae. What is the BEST explanation for this observation? A. The spores inherit half their genes from each parent. B. The spores inherit haploid nuclei from their parents. C. The spores inherit mutations as a result of meiosis. D. The spores inherit mutations as a result of mitosis.arrow_forwardHow does the stigma help Chlamydomonas survive?arrow_forwardThis figure summarises the life cycle of a seed plant.
