Another set of ESAIMs (north-ESAIMs) was ascertained using the results of the first PC scores of the “northern” European only analysis. We selected two disparate sets of individuals comprised of 93 and 132 individuals, by randomly selecting half of the individuals with PC scores one standard deviation above the mean and half of the individuals with PC scores one standard deviation below the mean. We used this procedure to provide both a distribution of allele frequencies in the disparate individual sets as well as maintain a well distributed set of individuals for evaluating the functional performance of the putative north-ESAIMs. These ESAIMs were then selected using the same method (In values) and criterion (minimum inter-SNP distance = 500 kb). We initially examined the best 1250 north-ESAIMs with 1608 individuals that had not been included in any of the ESAIM selections. Initial evaluation of this north-ESAIM set showed a distortion of the PCA in which the individuals were divided in three groups diagonally across the first two axes. Deletion of markers within the Chromosome 8 inversion (see above) resulted in a
