[Biodemographical study in the Island of Pascua].
The aim of this study was to know the degree of miscegenation in the Easter Island population. One hundred two weddings carried out between 1987 and 1991 were recorded and the proportion of marriages between islanders and immigrants was analyzed. Also, ABO and Rh blood groups of all deliveries occurred between 1988 and 1991 were compiled. There was a particular tendency of islanders to marry with immigrants and the proportion of miscegenation was 75.5%. Additionally a decline in the frequency of A blood group is observed, comparing results from studies performed since 1932 up to date.
