Additional file 4: of Copy number variations in Friesian horses and genetic risk factors for insect bite hypersensitivity

Abstract

Regional association plot (ECA20) of insect bite hypersensitivity in Friesian horses. Significance level based on allele frequency differences between cases (n = 141) and controls (n = 135) using a χ2-test (1df). The horizontal red line is the Bonferroni corrected significance level (P-value = 1.63 × 10− 7). (DOCX 27 kb
