Cumulative frequency graph of variant numbers for chromosomes 27 (a) and 2 (b) in female and male chickens for genomic variant enrichment analysis. Chromosomes 2 and 27 (Fig. 2) were selected in order to draw the cumulative frequencies graph of variants along the chromosome. It is shown by Figure (a) that the most variants enrichments are available in the range of 2692–1 × 106 base pairs (separated with horizontal line) of chromosome 27. A total of 234 variants was recognized on chromosome 27, and 100 (42.72%) variants were also located in the range of 2692–1 × 106 region. Figure (b) indicates that 17891 variants were recognized on chromosome 2, but 7600 variants (43%) were located in the range of 41 × 106–81 × 106 (27% of chromosome length) base pairs. Finally, these regions with the highest density of variation were selected for the identification of candidate genes.
