Diploid nuclei of the ascomycete Neurospora crassa contain 14 chromosomes. A single diploid cell in an ascus will undergo one round of meiosis, followed in each of the daughter cells by one round of mitosis, producing a total of eight ascospores. What is the ploidy of a single mature ascospore?

haploid

Explanation:

The ploidy level of a single mature ascospore is haploid with half the number of chromosome present in a single diploid cell.

Ascospore are produced by meiotic division of the single diploid cell and meiosis leads to the production of haploid cells because it involves the reduction of chromosome number.

Hence, if the diploid cell with 14 chromosomes undergo meiosis, it will give rise to haploid cells with half the number of chromosome (7) of the diploid cell.
