The Genetic Structure of the Population of the Koplik Municipality Calculated by the Isonomy

Abstract

The main focus of this study is the human population of the Municipality of Koplik,in Albania. The city of Koplik  is situated 17 km at the North of Shkodra city,in Albania. The genetic structure and connections among the inhabitants of Koplik, have been studied according to the distribution of the surnames of 18831 individuals, identified by 652 surnames, which resulted from the compilation of the genealogical trees.The coefficient of kinship was calculated, because of the isonomy of the case, along with evaluations of the ? of Fisher as indicator of the surname variety, evaluations of Fst inbreeding coefficients and evaluations of the Karlin-McGregor`s coefficient. The surname distribution has been calculated based on the logarithm of the surname number and the number of the times such surname is identified.

All these parameters have been calculated by means of the data extracted from the genealogical trees in three different methods, based on the surnames inherited from the father, from the mother and a another one, based on casual distribution of the surnames of the same persons,but without considering the genealogical relationship.All these methods show a high value of kinship, but when the three methods are compared, the results have obvious differences. For instance, the value Fisher ? was calculated by the Pedigree from the father ?=98.27, the mother ?=61.478, and from the casual distribution  ?=110.86. The value of the a of Fisher (?= 98.27) for this population, indicates high rates of kinship among the population of Koplik. A lower value of the ? coefficient from the mother side, can be easily explained with the fact that the kiniship in the marriages starting from the mother, is much higher than the one started from the father.
