Position of the SNP on chromosome 16.

The p-values after additive logistic regression with sex as a covariate and Bonferroni correction for horses in population 1, population 2, both populations together, and both populations together with a mixed model using the relationship matrix derived from pedigrees (negative log p-values are adjacently listed in parentheses).
