obsolete formation of azygotic ascus upon sporulation (obsolete FYPO:0000279)
OBSOLETE. A sporulation phenotype in which azygotic asci form following conjugation and subsequent sporulation. Azygotic ascus formation occurs when meiosis takes place within a diploid cell rather than in a zygote produced by sporulation. Zygotes can resume vegetative growth and form colonies of diploid cells if returned to rich media before commitment to meiosis; under nitrogen starvation, diploid cells heterozygous for mating type will undergo azygotic meiosis. Azygotic asci have a characteristic linear morphology resembling that of a single vegetatively growing cell.
