Two samples representing the Moslem and Christian communities of Jorda
n were examined for the polymorphic serum proteins AHSG, BF, FXIIIB, C
C, HP, PI, PLG, and TF. The results revealed similar allele distributi
ons, and low interpopulation differentiation (G(ST) = 0.0004) between
the two communities. The low HP1S (<0.12) allele frequencies and the
comparatively high PLGB (>0.40) and BF*S.07 (congruent to 0.05) frequ
encies are characteristic of the populations of this region.
