In his own abstract, A. Pruessner presents the geographical distribution of the autosomal inheritance of Finnish ydna. I have been waiting for academic research on this topic for a long time. What is being said now about the division of the N haplogroup into eastern and southwestern groups has been known for more than 10 years based on Ftdna's project data, so the presentation does not bring much new information to those interested in the matter. Pruessner's abstract does not say much about the geography of other haplogroups. Of course, for example I1 forms geographical clusters, but mainly from a common Finnish root. On the other hand, the origin of the N1 clusters refers to different angles of entry into the Finnish area. Inspired by Pruessner's presentation, I decided to do a PCA analysis using Finnish samples from the 1000genones project as data. The data includes 38 male samples out of a total of 99 samples. Due to the brevity of the ydna data in the material, I cut the definition to two characters (N1, I1, R1, one I2 removed), even if a more precise result would have been possible in some of the samples. I also did the same test with the narrower Eurogenes data. As a final conclusion, excluding ouliers in R1 and N1, two in both, it can be stated that the autosomal distribution of all yDna groups seems to be more or less similar in the entire Finnish population, although the narrower Eurogenes data points I1 towards Scandinavia and R1 towards Eastern Europe.
