Listed are the significant p-values (p<0.05) from Mann-Whitney U-test comparing the distribution of pairwise D' values within each distance class for Xq13 or Xp22 markers and the baseline distribution D'BASE estimates calculated between unlinked loci for each population. Significant difference indicates that LD in the studied region is exceeding the background-level LD between unlinked markers on X chromosome.
*
In Swedes, the significant p-value for Xp22 markers 5-10 Mb apart arises from HIGHER distribution of D' values between UNLINKED markers compared to pairwise D' values in this distance class. Blanks – non-significant p-values
