Fig. 3From: Polygenic analysis of very high acetic acid tolerance in the yeast Saccharomyces cerevisiae reveals a complex genetic background and several new causative allelesFine mapping and linkage analysis of QTL1 on chromosome VII. a SNP variant frequency for selected SNPs in QTL1 and corresponding p values. b Subdivision of QTL1 into five gene blocks for construction of pairs of hemizygous hybrid strains for evaluation by bulk-RHA. A detailed view of the nine genes present in the causative block 3 is shown at the bottom. Causative blocks and genes are indicated in redBack to article page
