Genomic distribution of the selective sweeps. The grey bars represent chromosomes with their lengths in Mb on the November 2011 (galGal4) genome assembly. The small blue dots indicate the locations of the 252 genotyped markers that passed quality control. The coloured bars connecting the dots on the chromosomes illustrate the 99 independently segregating regions that were tested for association with 56-day body weight in the F₁₅ generation of the Virginia Advanced Intercross Line. The centre of each selective sweep is indicated by its physical position in Mb. The colour of the bars indicate their genetic map lengths (cM, Haldane) in the F₁₅ generation and the extension of their physical map lengths (Mb)
