The genetic polymorphism of two salivary enzymes (esterase and a-amyla
se) was studied in individuals from eight districts of Greece. The poo
led gene frequencies were: Set(s) = 0.63, Set(F) = 0.37, AMY(1) = 0.87
, AMY(2) = 0.10, AMY(3) = 0.02, and AMY(4) = 0.01. There was no intrap
opulation heterogeneity, while there was a significant difference betw
een the Greeks and the few other European populations studied.
