This is just another utility which calculates percentages of admixture from autosomal genome data from FamilyTreeDNA Family Finder (.csv files) or 23AndMe (.txt files), using EM algorythm and using Calculator input files from Dodecad Ancestry Project (dodecad.blogspot.com). It is made in April 2014. There is not need for any conversion of format, you can just select your genotype file, ‘.par’ file...

On internet could be found many autosomal Principal Component Analysis charts, but would be no harm if we offer another one to fans of genetic genealogy. For this one are used many genomes from publicly available collections and works, like HGDP, HGP, Behar et al, Yunusbayev et al (2011), 1000 Genomes, Hellenthal at al (2014), Western Balkans (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0105090), and others. Beside them,...

Our code which calculates several first axis of Principal Component Analysis (PCA) from autosomal data has been made in September 2013. Now is viewer for axis data calculated by it available to fans of genetic genealogy, like pictures of 2016 calculation which were displayed earlier in “Autosomal PCA charts of Europe, Near East and Mediterranean”.In NevGen Tools is included file “PCA of Europe and...

NevGen probability Calculator of Time to Most Recent Common Ancestor (further, just “TMRCA Calculator”) has been written in February 2013 (it’s core for calculation), but was available to several people who worked with it from December 2014, when user interface for it was written. Before that time, it worked only by entering haplotype data into source code. Something must be...

We hope this can be useful to any layman or enthusiast of Genetic Geneology who wants to quickly learn about distribution of main haplogroups in Europe. Beside displaying distribution of main haplogroups, this charts are also intended for easy comparision of haplogroup frequencies among countries/peoples of Europe. Since frequencies for many countries/peoples are made with small number of available haplotypes,...

(last updated on January 10th, 2018.) Experienced genetic genealogists know that haplotypes of some subclades are relatively easy to be confidently predicted on some set of markers. For example, haplotypes belonging to R1b subclades L226 and M222 are easily recognisable even on 37 markers, and accordingly haplotypes of those two subclades are easy to distinguish from haplotypes of any other...
