Genome-wide association study for the polled phenotype in JT goats based on a linear mixed model. A mixed-model based GWAS for the polled phenotype in 45 JT goats that included 32 female, nine male, and four PIS-affected individuals. Manhattan plot of the association of 13,980,209 biallelic SNPs on autosomes 1–29 with the polled phenotype. The chromosomes are plotted separately by color. The horizontal dashed line indicates the genome-wide Bonferroni-corrected significance level
