Tim Janzen likewise has built-up a chart demonstrating the chances of confirmed genealogical relationship for every single cM tolerance increasing for the step one cM increments creating at six cMs and you may going up 2 hundred cMs. The fresh chart may be installed given that a stick out document out of this link. So it graph relates to non-endogamous populations. While using the chart in order to anticipate matchmaking from Relatives Finder research make an effort to eliminate the data for everyone locations lower than eight cMs.
Tim Janzen also has provided data toward number of SNPs mutual for different dating according to research by the 23andMe Compare Genes means:
- Parent-child pairs express ranging from % and you may % away from SNPs (50% out of DNA in accordance)
- Siblings express ranging from % and % out-of SNPs (50% of DNA in common)
- Uncle/aunt-niece/nephew pairs express ranging from % and you may % away from SNPs (25% of DNA in common)
- Grandparent-granddaughter pairs share ranging from % and % from SNPs (25% of DNA in keeping)
- Basic cousins and you can great-uncle/great aunt-grandniece/grandnephew sets express % and you may % out-of SNPs (12.5% regarding DNA in common)
- Very first cousins immediately following removed display california 75.5% regarding SNPs (6.25% out-of DNA in accordance)
- 2nd cousins and earliest cousins twice-removed show california 75% out-of SNPs (3.125% off DNA in accordance)
- Not related individuals of Western european origin share 73-74.6% off SNPs
