Fig. 3From: Polygenic analysis and targeted improvement of the complex trait of high acetic acid tolerance in the yeast Saccharomyces cerevisiae QTL mapping with selected SNPs in the individual segregants. Selected SNPs in QTL1 (a) and QTL2 (b) were scored with allele-specific PCR, the SNP variant frequency and the corresponding p values were calculated, and the p values were plotted over the length of the chromosomes, XIII for QTL1 (a) and XVI for QTL2 (b)Back to article page
