title: Rh system in the Lucca province (Italy): temporal and spatial variations.
abstract: Phenotype and gene frequency distributions of the Rh system in the province of Lucca (Italy) are reported and discussed considering their diachronic and geographic variations. The data were collected in blood transfusion centers and refer to a total of 13,856 individuals. Analysis by chi 2- and R-matrix methods point to a highly significant genetic heterogeneity among the population subsamples through time. The results are discussed in relation to sample representativeness and to the main geographic and demographic characteristics of the province.
