Agrupamientos poblacionales en Uruguay inferidos en base a la distribución de apellidos
Recientemente publicamos el análisis de los apellidos del Padrón Electoral de 2010 de la República Oriental del Uruguay a través de distancias isonímicas, basado en sus 19 departamentos y las 171 comparaciones posibles entre estos, lo que mostró la forma-ción de dos grandes agrupamientos en el sur, y otros pocos vinculados en el norte y este. El objetivo del presente trabajo es detallar el análisis de las distancias isonímicas utilizando la distr…
The structure and migration patterns of the population of Uruguay through isonymy
Surname distribution can be a useful tool for studying the genetic structure of a human population. In South America, the Uruguay population has traditionally been considered to be of European ancestry, despite its trihybrid origin, as proved through genetics. The aim of this study was to investigate the structure of the Uruguayan population, resulting from population movements and surname drift in the country. The distribution of the surnames of…
Consanguinity by Random Isonymy and Socioeconomic Development in Argentina: A Population Study
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…
Isonymic Relations in the Bolivia-Argentina Border Region
When migrating, people carry their cultural and genetic history, changing both the transmitting and the receiving populations. This phenomenon changes the structure of the population of a country. The question is how to analyze the impact on the border region. A demographic and geopolitical analysis of borders requires an interdisciplinary approach. An isonymic analysis can be a useful tool. Surnames are part of cultural history, sociocultural fe…

Surnames in Chile: A study of the population of Chile through isonymy
In Chile, the Hispanic dual surname system is used. To describe the isonymic structure of this country, the distribution of 16,277,255 surnames of 8,178,209 persons was studied in the 15 regions, the 54 provinces, and the 346 communes of the nation. The number of different surnames found was 72,667. Effective surname number (Fisher's α) for the entire country was 309.0, the average for regions was 240.8 ± 17.6, for provinces 209.2 ± 8.9, and for …
Surnames in Bolivia: A study of the population of Bolivia through isonymy
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…
Surnames in Siberia: A study of the population of Yakutia through isonymy
We studied the isonymic structure of the Republic of Sakha (Yakutia), in the Russian Federation, using the surname distributions of 491,259 citizens above 18 years registered as residents in 2002. These were distributed in 35 districts and 497 towns and settlements of the Republic. The number of different surnames was 44,625. Matrices of isonymic distances between the 35 districts were tested for correlation with the geographic distance between t…
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…
Admixture estimates based on ABO, Rh and nine STRs in two Venezuelan regions
(i) All systems were in Hardy-Weinberg equilibrium, except the Rh blood group of the Central-Western Region; (ii) the European contribution is high in both groups; (iii) in the dendrogram and PCA, the studied populations appear close to other admixed populations, and their relative position with regard to the three parental populations coincides with the admixture analysis
Isonymic structure of the Argentine Northwest
Surname distribution may be used as a substitute for quantitative information on the genetic structure of human populations due to panmictic deviations. This study analysed the isonymic structure of the Argentine Northwest (ANW) populations. Surname distribution of 2,576,548 voters (year 2001) in the 117 departments of the region was analysed. Fisher's alpha and coefficient of random relationship by isonymy were estimated. A dendrogram of the 117…
Admixture Estimates for Caracas, Venezuela, Based on Autosomal, Y-Chromosome, and mtDNA Markers
The present Venezuelan population is the product of admixture of Amerindians, Europeans, and Africans, a process that was not homogeneous throughout the country. Blood groups, short tandem repeats (STRs), mtDNA, and Y-chromosome markers have been used successfully in admixture studies, but few such studies have been conducted in Venezuela. In this study we aim to estimate the admixture components of samples from two different socioeconomic levels…
Surnames in Argentina: A population study through isonymy
In order to study the isonymic structure of Argentina, the surname distributions of 22.6 million electors registered for the year 2001 were analyzed in the 24 districts (distritos) and 541 municipalities (municipios) of the country. The number of different surnames found was 414,441. Matrices of isonymic distances between districts were constructed and tested for correlation with the geographic distance between the capital towns of the districts.…
Admixture estimates for Churuguara, a Venezuelan town in the State of Falcón
Results of the admixture analysis are consistent with those obtained with two dendrograms and principal component analyses, suggesting that the strong initial Amerindian component of 500 years ago has been diluted by the continuous flow of European genes, mainly Spanish, to this region
Beta‐globin gene cluster haplotypes as evidence of African gene flow to the northeastern coast of Venezuela
In order to study the origin of mutation HBB*S in Sucre and Anzoátegui states and the genetic affinities of these Venezuelan populations with other human groups, the β‐globin gene cluster haplotypes were determined for 28 sickle cell and/or S‐beta thalassemia patients and for 37 individuals with normal hematological parameters. Bantu, Benin, Senegal, and atypical haplotypes were identified in 50%, 36%, 2%, and 12% of the HBB*S chromosomes, respec…
Behavior of loci D1S1656 and D12S391 in a sample from Maracaibo, Venezuela
Two recently reported short tandem repeat polymorphisms characterized by PCR, D1S1656 and D12S391, were investigated in a sample from Maracaibo, an admixed population of Venezuela, in order to evaluate their application in forensic and population genetics studies. The unbiased heterozygosities were 0.9011 and 0.8444 for locus D1S1656 and D12S391, respectively. The joint discrimination power and joint probability of exclusion were 0.99972 and 0.93…
The names of Spain: A study of the isonymy structure of Spain
In order to estimate the isonymy structure of Spain, we studied surname distribution in 283 Spanish towns based on 3.625 million telephone users selected from 6.328 million users, downloaded from a commercial CD‐ROM which contains all 13 million users in the country. Since in Spain the surname is made by the paternal and the maternal surname, it was possible to classify surnames according to parental origin. Two matrices of isonymy distances, one…
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…
Isonymy and the genetic structure of Switzerland. II. Isolation by distance
Isolation by distance in Switzerland was detected comparing the surname distributions between Cantons. The decay of isonymy with geographic distance between Cantons was consistent with Malecot's exponential decay of kinship. Lasker's distance was defined as the negative value of the logarithm of isonymy between localities, and it was found that it is linearly and significantly correlated with the log of geographic distance, both within and betwee…
Correlations between Isonymy Parameters
Several parameters of genetic and anthropological interest are commonly estimated in the analysis of the surnames' distribution in human populations. Among these parameters, the most important for population structure is unbiased Isonymy, equivalent to 4 times the value of Fst, the random component of inbreeding in a group. Fisher's α estimates the wealth of surnames in a group, and Karlin-McGregorv is considered proportional to migration rates. …
Isonymy and the genetic structure of Switzerland I. The distributions of surnames
The surname distribution of the population of Switzerland was studied using a sample of 1,702,000 private users registered for the year 1994 in the Helvetic Telephone Directory. These users were distributed in four linguistic areas, in 26 Cantons and 271 Communes of the Confederation. Estimates of unbiased random isonymy, of Fisher's alpha, an indicator of abundance of surnames converging to the allele effective number in standard genetic polymor…
Isonymy and the genetic structure of Sicily
The genetic structure of Sicily was analysed through the distribution of surnames of 758,793 users registered in the Italian Telephone Company, corresponding to 371 communes of the island. Estimates of the coefficient of consanguinity due to random isonymy, of Fisher's a , an indicator of abundance of surnames, and of Karlin–McGregor's v , an indicator of immigration rates, were obtained for each commune. Four different estimates of genetic dista…
Genetic distance estimated through surname frequencies of 37 counties from the state of Lara, Venezuela
Genetic distances between all possible pairs of counties ( n = 37) in the state of Lara, Venezuela were calculated using surname frequencies and the Euclidean distance as estimator. In general, Euclidean distances were smaller between counties closer together, and the product moment correlation between geographic and Euclidean distances was 0·49 ( p
Microevolution in Perugia: Isonymy 1890–1990
The distribution of surnames in the population of the Comune of Perugia, as it existed in the memory banks of the Municipality Computer in autumn 1991, was studied by age and place of birth. Fisher's α and Karlin-McGregor's v were estimated in the total population, in persons born before 1901, and in persons born in the nine decades thereafter, ending with the period 1981–1991, for immigrants and for natives of Perugia, respectively. The wealth o…
Isonymy structure of four Venezuelan States
The isonymy structure of four Venezuelan States-Falcón, Mérida, Nueva Esparta and Yaracuy-was studied using the surnames of the Venezuelan register of electors updated in 1984. The surname distributions of 155 counties were obtained and, for each county, estimates of consanguinity due to random isonymy and Fisher's alpha were calculated. It was shown that for large sample sizes the inverse of Fisher's alpha is identical to the unbiased estimate o…
