[Computer technology of the genogeographic study of the gene pool. I. Statistical information from the genogeographic...

General statistical information that can be derived from an electronic map and listed in its legend is reviewed. Certain map information (extrema, mean and variance of mapped values, the number of initial and mapped values, their statistical distributions) can be used in analysis not only of gene pool, but also of phene pool maps. Another portion of map information, on total gene diversity, heterozygosity, and interpopulation differentiation, is important for consequent detailed analysis of a gene pool. Statistical information that is derived from a genogeographic map aids understanding of the content of a map and is used in comparative quantitative analysis of different regions and various mapped parameters. The possibilities for interpretation of statistical information of genogeographic maps are shown using the human gene pool as an example. Maps of frequencies of ABO-O and Rh-d blood group genes in three hierarchically subordinate gene pools of native inhabitants of Belarus, the Black Sea-Baltic region, and northeast Eurasia are presented for this purpose.
