Scatterplot of the first two principal component axis for intermediate wheatgrass genets, made from principal component analysis on the marker matrix, n = 6,199 genets, markers = 23,495. Each point is an individual genet that is color coded by cycle, with the 2nd principal component providing separation between the UMN and TLI breeding programs at the dashed line. Total variance explained by each principal component is listed on the axis.
