#13 Complete the sentence about fungus reproduction. (in each underlined space people pick the word or phrase that best completes the sentance) (words are in bold) When fungi reproduce asexually, they make spores through binary fission OR mitosis OR meiosis , which results in identical OR non-identical cells. This means that the offspring will be OR not be genetically identical to each other and to their parent.
