Manhattan plots of the genomic selection signature in response to cold temperature. A p-values were obtained from an adapted CMH test [49] comparing the founder generation (F0) to the most advanced (F51) generation. The dotted line indicates the significance threshold (p-value < 0.05 after correction for multiple testing). B, C A close-up of the Manhattan plot in panel A for chromosomes 2 and 3. Each selected haplotype block and the corresponding candidate SNPs are shown in a distinct color. Numbered bars above the Manhattan plot indicate the position of the selected haplotype blocks. Some blocks, which can be further subdivided by the analysis of earlier time points, are labeled with letters (e.g., 10a and 10b). SNPs with significant allele frequency changes in both, hot and cold, selection regimes (shared SNPs) are colored in dark red
