Ability of Ip index to distinguish between the ukrainian populations of the regional level
Aims. An important indicator of a marker is its resolving power, i.e. the ability to differentiate the data. Therefore the goal of this study is to determine how using surnames allows to differentiate the gene pool of the Ukrainian population living in regions with different demographic history. Methods. Surnames in a nationwide ukrainian list arranged in descending order of frequency and they are assigned in rank. For each region average Location Index is calculated and compared with the all population of Ukraine. Results. The distribution of frequent surnames across the border of the Ukraine including its five regions is studied. We established that the Location Index differs the average Ukrainian values from the Western region (I10= 22.5, I20= 37.1) in a greater extent than Central region (I10= 6.3, I20= 11.1). Central, Southern, Northern and Eastern regions form a cluster, where the Eastern region (I10= 13.0, I20= 24.2) is most distant from the average Ukrainian values. Conclusions. Ukrainian surnames can serve as an indicator reflecting the characteristics of the regions of the country. The Location Index indicates the Western region as most specific. Other regions form the cluster close to the nationwide ukrainian by the value of the Location Index. The most "typical" is the Central region.
