Consanguinity by Random Isonymy and Socioeconomic Development in Argentina
In human populations various flexible, labile and interdependent structures (genetic, demographic, socioeconomic) co-exist, each of which can be organized in an hierarchical order corresponding to administrative entities. The relationship between consanguinity, as estimated by random isonymy ( F ST ), and socioeconomic conditions was analysed at different levels of political and administrative organization in Argentina. From the surnames of 22,66…
Random inbreeding, isonymy, and population isolates in Argentina
Surnames in Bolivia
In Bolivia, the Hispanic dual surname system is used. To describe the isonymic structure of Bolivia, the surname distribution of 12,139,448 persons registered in the 2006 census data was studied in 9 districts and 112 provinces of the nation, for a total of 23,244,064 surnames. The number of different surnames found was 174,922. Matrices of isonymic distances between the administrative units (districts and provinces) were constructed and tested f…
Isonymy Structure of Buenos Aires City
The isonymy structure of Buenos Aires was studied based on its surname frequency. Information on 2,552,359 voters of the 28 Buenos Aires districts was used to estimate Lasker's coefficient of relationship by isonymy (R(i)), surname diversity according to Fisher's alpha, the coefficient of consanguinity resulting from random isonymy (F), and Nei's, Lasker's and the Euclidean isonymy distances. These distances were correlated with geographic distan…
Isonymy structure of USA population
The isonymy structure of the 48 states of the continental United States of America was studied using the surname distributions of 18 million telephone users, distributed in 247 towns. The shortest linear distance between nearest neighbor towns included in the sample was 12.0 km. The largest distance was 4,577 km. The number of different surnames found in the whole analysis was 899,585. Lasker's distance was found to be significantly but weakly co…
Genetic Structures and Linguistic Boundaries in Italy
The amount of genetic data (sequences, gene frequencies, and isonymy) available for the Province of Ferrara, Italy, makes this area one of the world's best known. In an effort to infer the underlying demographic processes, we studied the province's population structure by comparing geological, palaeoclimatic, archeological, historical, and linguistic data. This multilevel approach allowed us to date some characteristics of the population structur…
Surname frequency and the isonymy structure of Venezuela
Isonymy in Venezuela was studied analyzing the surnames of 3.9 million adults 40 years and older, selected from the register of electors updated in 1991. The electors were not differentiated by sex and represented all 22 states of Venezuela and its Federal District. The states of Nueva Esparta, an island, and Mérida, in the Venezuelan Andes, have the highest coefficients of microdifferentiation (R(ST)) and of inbreeding due to random isonymy. The…
Distribution of ABO Blood Groups on the Indian Subcontinent
This paper attempts a comprehensive statistical analysis of the O-A-B-AB blood-group frequencies collected from the Indian subcontinent. The objective is to examine the variation in ABO gene frequencies among populations using statistical tests of homogeneity and single-linkage cluster analysis. In all, 899 sets of phenotype frequency data were examined. Of these, 405, each based on a sample of at least 100 individuals and in conformity with Hard…
