Question
During sexual reproduction in ascomycetes, what occurs in each ascus after pairs of nuclei from male and female strains migrate into ascogenous hyphae?
Correct Answer
Option C is the correct answer.
Detailed Explanation
In each ascus, two or more haploid ascospores fuse their nuclei in karyogamy. The resulting diploid nucleus then gives rise to haploid nuclei by meiosis. The ascospores are subsequently released, germinate, and form new hyphae.
Hint
Follow the sequence: nuclear fusion first, then reduction division to restore haploidy.
