Tim Janzen has also gathered a map indicating the probability of a given genealogical relationships each cM threshold rising within the 1 cM increments doing at 6 cMs and increasing 200 cMs. The chart tends to be downloaded while the a get noticed file from this connect. So it graph relates to low-endogamous populations. While using the chart to expect relationships of Relatives Finder investigation just be sure to eliminate the investigation for all areas below seven cMs.
Tim Janzen also offers given study with the quantity of SNPs common for different matchmaking in line with the 23andMe Compare Genes function:
- Parent-child sets share between % and you can % out-of SNPs (50% out of DNA in common)
- Sisters share ranging from % and you will % from SNPs (50% out of DNA in keeping)
- Uncle/aunt-niece/nephew sets show ranging from % and you can % regarding SNPs (25% regarding DNA in keeping)
- Grandparent-granddaughter pairs share anywhere between % and you may % off SNPs (25% off DNA in accordance)
- Basic cousins and you can great uncle/great aunt-grandniece/grandnephew sets show % and % from SNPs (a dozen.5% out of DNA in common)
- Very first cousins immediately following got rid of show california 75.5% of SNPs (six.25% regarding DNA in keeping)
- 2nd cousins and you may first cousins twice-removed display california 75% out-of SNPs (step three.125% away from DNA in common)
- Unrelated folks of European origin show 73-74.6% of SNPs

Leah Larkin has composed a post into limitations of predicting dating playing with DNA with a dining table out-of dating range in the DNA Investigators group and you may a chart showing ranges mainly based to the simulations of the AncestryDNA. Read more
