↵^{a} See column 1 of Table 1 for names of strains used.
↵^{b} Frequency of T plus NPD tetrads for interval indicated.
↵^{c} Observed frequency of tetrads that are either T or NPD for both the URA3-LEU2 and the LEU2-MAT intervals.
↵^{d} “Expected” is the product of the frequencies given for the URA3-LEU2 interval and the LEU2-MAT interval.
↵^{e} P values reflect the likelihood that the difference between the expected and observed frequencies is attributable to chance as determined by a χ^{2} test.
