Tim Janzen has gathered a map indicating the possibilities of a given genealogical dating for each cM endurance increasing into the step 1 cM increments starting at six cMs and increasing 200 cMs. The new graph is generally installed as the a shine file using this hook up. That it chart pertains to low-endogamous communities. While using the graph to anticipate relationships away from Nearest and dearest Finder research attempt to eliminate the study for all areas significantly less than eight cMs.
Tim Janzen is served by considering investigation into number of SNPs common for several relationship in line with the 23andMe Compare Genetics form:
- Parent-child sets express anywhere between % and % out of SNPs (50% from DNA in accordance)
- Sisters show between % and you will % of SNPs (50% off DNA in common)
- Uncle/aunt-niece/nephew sets express between % and you will % regarding SNPs (25% from DNA in keeping)
- Grandparent-grandchild pairs display ranging from % and you will % out of SNPs (25% regarding DNA in common)
- Earliest cousins and great uncle/great-aunt-grandniece/grandnephew sets show % and you will % away from SNPs (12.5% off DNA in accordance)
- Basic cousins just after eliminated show ca 75.5% from SNPs (six.25% of DNA in accordance)
- 2nd cousins and basic cousins twice-removed show california 75% out-of SNPs (step three.125% regarding DNA in common)
- Not related people of Western european origin express 73-74.6% of SNPs
