Figure 1

Principal component (PC) analysis plot of distribution of three IR+ pools and three IR− pools. The amount of variance explained by the first two component, PC1 and PC2, is 42% and 16%, respectively. As the percentage of explained variance in the PC2 compared with the PC1 component is low, the spread along the y axis alone does not indicate the high within-group sample variability (that is, low technical variance).As IR+ and IR− clusters are far apart, this indicates true global genetic differences (biological variance) between the groups.
