Scatterplot of the first 2 principle components (PC) of the genomic relationship matrix. Each dot represents a single animal (n = 2,013 in total) in the sample and each color corresponds to 1 of the top 10 insemination boars. All other boars are summarized within the magenta color. The percent values on the axis labels account for the amount of variance explained by the respective principle component of the genomic relationship matrix.
