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.
