Fig. 5From: 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 QTL2 on chromosome XI. a SNP variant frequency for selected SNPs in QTL2 and corresponding p values. b Subdivision of QTL2 into three gene blocks, of which block 2 only contains the TRT2 gene, for construction of pairs of hemizygous hybrid strains for evaluation by bulk- or single gene-RHA. Causative block and gene are indicated in redBack to article page
