- Figure 24.14 Which of the following statements is true? A dikaryotic ascus that forms in the ascocarp undergoes karyogamy, meiosis, and mitosis to form eight ascospores. A diploid ascus that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A haploid zygote that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A dikaryotic ascus that forms in the ascocarp undergoes plasmogamy, meiosis, and mitosis to form eight ascospores.Both antheridia and archegonia are on the same gametophyte.
