Abstract
The coefficient of relationship by isonymy Ri was obteined using paternal and maternal surnames of individuals in four black Venezuelan populations. The analysis of eight Ri values obtained from different combinations of surnames within each population and between population in two periods of time (1900–1920 and 1944–1967) show that: 1) Higher values of Ri are those that include combinations of maternal surnames, 2) Ri values of the second period are higher than those shown in the first, 3) No correlation was observed between Ri values and geographic distance. These results indicate that there is a tendency towards matrilocal behavior and show agreement with the degree of isolation of each population. The use of four surnames for estimating the coefficient of relationship by isonymy Ri, permits better comparisons of the relationship between and within groups and gives detailed information of the population structure.
