Genetic Structure of a Rural Region in Spain: Distribution of Surnames and Gene Flow
The biodemography of isolated populations with a subsistence economy is of special interest because the conditions to which the populations have been subjected are similar to those present over a large part of the history of our species, and hence the conclusions drawn can be extrapolated to other similar populations. In the present work, we used two recently employed techniques (self-organizing maps and Monmonier's algorithm) to study the geneti…
Differential reproductive pattern in a rural Spanish region (La Cabrera, León): Consequences for potential natural selection
La Cabrera (northwest Spain), the study area, during most of the period examined (1880-1969) was characterized by high inbreeding levels and internal subdivision, which probably favoured the action of genetic drift and genetic differentiation. Indices regarding potential selection based on variables related to the reproductive pattern of reconstituted families with complete reproductive cycles (n = 1498) were analysed. A traditional demographic c…
Genetic Structure of La Cabrera, Spain, from Surnames and Migration Matrices
The genetic structure of La Cabrera (province of Léon, Spain), a highly isolated and inbred population (alpha3 = 0.00482), is analyzed by applying multivariate methods (nonmetric multidimensional scaling, Mantel test, Monmonier's algorithm) to different biodemographic data sets. Isonymy, parent-offspring migration (total, males, females), and marital migration matrices were obtained from 5,714 marriages recorded in 37 parishes (clustered in 4 mun…
Migration matrices and surnames in populations with different isolation patterns: Val di Lima (Italian Apennines), Val di Sole (Italian Alps), and La Cabrera (Spain)
Biodemographic methods are widely used to infer the genetic structure of human populations. In this study, we revise and standardize the procedures required by the migration matrix model of Malécot ([ 1950 ] Ann Univ Lyon Sci [A] 13: 37–60), testing it in large historical‐demographic databases of 85 populations from three mountain valleys with different degrees of isolation: Val di Lima (Italian Apennines, 21 parishes), Val di Sole, (Italian Alps…
Reproductive pattern in consanguineous and non-consanguineous marriages in La Cabrera, Spain
In the La Cabrera population, consanguinity appears as a socio-cultural process that affects the reproductive dynamic. Consanguinity modifies the marital structure and alters the reproductive pattern, prolonging the reproductive period, which results in a greater number of offspring. Lower infertility rates and the possible compensatory effect for infant mortality may reflect biological factors making the wife's reproductive period more efficient
Inbreeding Patterns in La Cabrera, Spain: Dispensations, Multiple Consanguinity Analysis, and Isonymy
Marital structure and inbreeding coefficients were analyzed in La Cabrera, an isolated mountain region in northwestern Spain. A total of 5,714 marriages were celebrated from 1880 to 1989 in the 37 parishes of the area. The total frequency of consanguineous marriages (up to the fourth degree) is 23.05%; multiple consanguineous marriages are remarkably common, reaching 5.43% of the total. The first cousin/second cousin ratio (referred to as kinship…
