Rates of reciprocal mitotic crossover in diploid strains homozygous and heterozygous for (GAA)n•(TTC)n tracts.

1As elsewhere in the text, GAA indicates that the (GAA)n tract is the lagging strand template, and TTC is the opposite orientation relative to the replication origin. In this column, the upper number represents the tract located in the PSL2–derived homologue and the bottom number represents the tract in the PSL5–derived homologue.2The average frequency of sectored colonies in 20 to 40 independent cultures was determined. This value was multiplied by two to calculate the rate of RCOs.3This strain was analyzed previously [15].
