Question

In Neurospora, $8$ ascospores are formed instead of $4$. This indicates.

• A. One meiosis
• B. Two meiosis
• C. Two mitosis
• D. Meiosis followed by mitosis

Answer 1

The correct option is D Meiosis followed by mitosis

Typically, a single ascus will contain eight ascospores. The eight spores are produced by meiosis followed by a mitotic division. Two meiotic divisions turn the original diploid zygote nucleus into four haploid ones.

So, the correct answer is 'Meiosis followed by mitosis'.
