Percent viability (n = 300) and chromosome loss were determined as described in Materials and Methods (N.D.) Not determined. 

^aStrain numbers listed first (e.g., KT1112) were haploids used for determining percent viability; second strain numbers (e.g., 1385) were homozygous diploids used for determining chromosome loss.
