Tim Janzen has also compiled a map proving the probability of a given genealogical dating for every cM threshold going up during the 1 cM increments undertaking at the six cMs and you can increasing 200 cMs. The brand new chart may be downloaded because a get noticed file out of this connect. This chart applies to non-endogamous populations. While using the chart so you can predict relationship off Family relations Finder data just be sure to remove the data for everybody segments around 7 cMs.
Tim Janzen also has provided studies to your amount of SNPs shared for several matchmaking in line with the 23andMe Compare Genes form:
- Parent-youngster sets share between % and you will % out of SNPs (50% away from DNA in common)
- Siblings express ranging from % and you may % away from SNPs (50% off DNA in common)
- Uncle/aunt-niece/nephew sets share anywhere between % and % out of SNPs (25% off DNA in keeping)
- Grandparent-granddaughter pairs express ranging from % and % from SNPs (25% regarding DNA in accordance)
- Earliest cousins and you will great uncle/great-aunt-grandniece/grandnephew sets share % and you may % of SNPs (twelve.5% of DNA in common)
- Earliest cousins immediately following removed show california 75.5% out-of SNPs (6.25% off DNA in accordance)
- Next cousins and you will very first cousins twice removed share ca 75% out-of SNPs (step three.125% of DNA in keeping)
- Unrelated people of European lineage show 73-74.6% off SNPs

Leah Larkin possess composed a post towards the restrictions off anticipating dating using DNA which has a desk of matchmaking ranges on the DNA Investigators group and you may a map proving ranges based to the simulations from the AncestryDNA.
