  • a Strains analyzed were BR4316 and BR4310.

  • b Tetrads in which three spores were viable and one spore was disomic for chromosome III were analyzed to determine whether the sister spore to the disome was viable.

  • c Disomes recovered from one-, two- and three-spore viable tetrads were scored for containing one or both centromere markers, representing the products of MI and MII missegregation events, respectively.
