From: Variants at the ASIP locus contribute to coat color darkening in Nellore cattle
Genome-wide association analysis for DHC in Nellore cattle. a A single major locus mapping to chromosome 13 was detected (highest associated SNP, BovineHD1300018322; \(p\) = 1.27 \(\times\) 10–35). b Peak associations were found in a region (dashed lines) spanning the ASIP (CHR13:63,662,796–63,668,123) and AHCY (CHR13:63,686,723–63,702,437) genes. c The alternative G allele was correlated with increased darkness of hair coat in an additive pattern (\(p\) = 1.42 \(\times\) 10–52). Heterozygotes had their median phenotypic value skewed towards the median of the AA genotypic class, revealing a potential dominance effect associated with the reference A allele (\(p\) = 1.84 \(\times\) 10–15)
