Figure 7.—

SAL1, CAT5, and MIP1 are QTGs that affect the petite frequency phenotype. Petite frequencies (as described in Figure 1) of strains containing each of the eight combinations of BY or RM alleles at the SAL1, CAT5, and MIP1 QTGs are presented. All eight strains (UCC8356–UCC8363 in Table 1) are haploid spores derived from a single diploid BY strain that was homozygous for MKT1-30G and heterozygous for SAL1/sal1-1, CAT5-91M/CAT5-91I, and MIP1-661T/MIP1-661A (see materials and methods). The BY and RM alleles of each gene are described in the Table 2 legend.
