Results of genetic heterogeneity test by comparing the means of the populations. Genetic heterogeneity was investigated by cumulative distribution functions and mean repeat array size of the MSRs for each population. The results of the genetic heterogeneity test by comparing the means of the populations are illustrated for each MSR. The populations are depicted as a circle describing their mean repeat array sizes in number of repeat units. Dashed lines indicate a significant difference between populations (p-value < 0.05) and solid lines a p-value < 0.01. Both RNU2 and DXZ4 showed similar means of repeat array sizes in the different populations, while the means of the other six MSRs were significantly different for at least two populations. Genetic heterogeneity was variable for the MSRs, where it depended on the MSR which populations showed similar mean array sizes or significant differences.
