How accurate is the DNA Originsâ¢ test? The DNA Originsâ¢ test provides your ancestral proportions based on years of collaborative research of populations representing 4 ancestral groups. This research identified 144 informative markers in our DNA, called Ancestry Informative Markers (AIMs).
the standard ancestry dna tests for tracing the paternal or maternal line is about $ 120 and this includes all the ancestry tools and services that are available at genebase advanced ancestry dna tests for both the paternal line and maternal line range from $ 200 to $ 300dna testing may either be conducted in a testing facility or a kit could be mailed to individuals according to huffingtonpost com a mail order kit from ancestry com will cost anywhere from $ 200 to $ 350ancestry dna is the latest dna testing service which employs some of the latest autosomal testing technology to revolutionize the way one discovers their family historypgrades which supplement the standard and the advanced ancestry dna tests range from $ 90 to $ 140 various combo ancestry dna kits which include the different combination of the paternal and the maternal line tests range anywhere from $ 240 to $ 400
