Population data on 5 non-CODIS STR loci (D10S1248, D22S1045, D2S441, D1S1656, D12S391) in a population sample from Brescia county (Northern Italy). 67% of the ethnicity was what I expected from my tree and family stories: English, Scottish, Welsh, and Irish. This very simple sentence is key to understanding your ethnicity estimate. As you can see from the centimorgan chart, a centimorgan range of 575 to 1330 could mean the DNA match is a first cousin, half aunt, or even a grandparent.

A stool DNA test finds cells in a stool sample. Typically, 15 markers are tested for matches, but conclusive answers can be reached with as few as six markers. 1. The allelic frequencies of four loci (D7S820, D13S317, TH01, TPOX) were compared with data sets from six Amazonian populations, seven Andean and two Panamanian populations previously reported (15-18).
