rad2Δ restores faithful chromosome segregation in the absence of Rec12

Strains with the complementing alleles ade6-216 and ade6-210 were crossed. Crosses were homozygous for the indicated rec12 and rad2 alleles. Complete genotypes are in Table 1S (see supplementary data at http://www.genetics.org/supplemental/).

Values are the means of five independent experiments ± SEM.

For series 24 and 25 crosses, the total number of heterozygous diploids was divided by the total viable spores from the five experiments. For series 22 crosses, no heterozygous diploids were observed; the upper 95% confidence limit was calculated on the basis of the Poisson distribution. For each cross in each experiment 147–442 colonies were counted.
