abolished meiosis II abolished zygotic meiosis II A cellular process phenotype in which the second meiotic nuclear division does not occur during a cycle of zygotic meiosis and sporulation. Zygotic meiosis and sporulation take place under conditions of continuous nitrogen starvation, in which haploid cells of the opposite mating types conjugate to form diploid zygotes that proceed immediately to undergo meiosis and sporulation. abolished zygotic second meiotic nuclear division 2015-08-07T12:01:35Z FYPO:0004799 midori abolished meiosis II during zygotic meiosis
