Additional file 18 of Across-breed analyses of genome-wide association studies for stature and mammary gland morphology in cattle reveal pleiotropic effects of the Friesian POLLED haplotype

Supplementary Material 18: Figure S17. Association testing for front teat position in Holstein (HOL) cattle with known POLLED genotype. The upper panel shows the results of an association study between imputed sequence variant genotypes on BTA1 and front teat position in 3397 HOL cows with known POLLED genotype. The lower panel shows the results of an association study between imputed sequence variant genotypes on BTA1 and front teat position in 3073 HOL cows not carrying the Friesian polled variant. The red symbol represents the most significantly associated marker from the across-breed meta-analysis.
