From: Linkage disequilibrium compared between five populations of domestic sheep
Linkage disequilibrium (x2') as a function of genetic distance. Each population is plotted in a separate panel. The absolute values of x2' (green circles) are plotted as a function of the genetic distance separating each marker pair (cM). Note the Y axis scale (x2') is not the same for each population. The mean value of x2' within defined distance bins is shown as horizontal green bars and contained within Table 2. The decay of LD modelled as a function of distance according to formula 3 is shown using black diamonds. Two significance thresholds are indicated using horizontal lines. The first represents the average x2' value obtained between non-syntenic marker pairs (orange line) while the second represents the 5% significance threshold (red line).
