Geographic variation analysis of the ABO and RH systems in Turkey.
In this study, we report the results of a geographical variation analysis on the gene frequencies of ABO and RH systems in 67 provinces of Turkey. The gene frequencies of A, O and RH(-), were subjected to spatial autocorrelation analysis and significant spatial autocorrelation coefficients were observed for each gene in the first distance class. The average I-correlogram for the three genes displayed a clinal pattern. The results also suggested a marked decrease in genetic similarity in relation to geographic distance.
