Genomic selection is being increasingly applied in many areas of livestock production. In Poultry, using a large-scale genotyping assay with the 56K snp-chip our group has implemented genomic selection for three generations in tandem with traditional BLUP selection to evaluate the merits of genomic selection. The program was implemented for three traits in two broiler lines. Previous studies have assessed the impact of selection based primarily on simulations of the SNP effects from theoretical distributions. Using data from this study, we compare genomic selection to traditional BLUP selection at the whole genome level, by assessing signatures of selection. Performing a genomic scan for signatures of ongoing selection can suggest genome regions of interest and in turn can suggest additional traits under selection, similar to natural selection mapping and hitchhiking mapping. We compare signatures of selection both within and between lines and evaluate the differences among the two selection regimes. Specifically, we look at differences in allele frequencies within lines, from the base population after three generations, to evaluate the differences in genomic regions under selection for each type of selection method. Using Fst statistics, we compare the divergence between the lines for the BLUP selected and the genomic selection lines after three generations of selection. We graphically illustrate the differences in the effects of selection methodologies within and between lines.
