Abstract/OtherAbstract:
Diploid yeast strains, homozygous for the mutation spo13, undergo a single-division meiosis and form dyads (two spores held together in one ascus). Dyad analysis of spo13/spo13 strains with centromere-linked markers on five different chromosomes and on a pair of human DNA YACs shows that: (a) in spo13 meiosis, chromosomes undergo mixed segregation, namely some chromosomes segregate reductionally whereas others, in the same cell, segregate equationally; (b) different chromosomes exhibit different segregation tendencies; (c) recombination between homologous chromosomes might not determine that a bivalent undergoes reductional rather than equational segregation.
