FTDNA ‘TiP’ is their program incorporating Y-STR marker specific mutation rates to |
|
|
increase the power and precision of Time to Most Recent Common Ancestor (TMRCA) |
|

estimates: https://www.familytreedna.com/learn/y-dna-testing/ftdna-tip-calculator |

TMRCA Calculations (Family Tree DNA 'TiP' using their Infinite Allelle Method) [51]: |
|
|
composite, comparing the test results with each other man (91.9% and 94.0% matches), |
|
|
knowing that we did not have a common ancestor in the last 6 or 7 generations, the |
|
|
probability that we shared a common ancestor within the last ‘n’ generations:. |
|
|
8 Generations: 25.02% - 34.41%; 12 G: 65.28% - 72.91%; 16 G: 86.55% - 91.27%; |
|
|
20 Generations: 95.37% - 97.61% (96.5%); 24 Generations: 98.53% - 99.42% (99%) |

Years per Generation: per isogg wiki, estimate 3 male generations in 100 years |
|
|
http://isogg.org/wiki/How_long_is_a_generation%3F_Science_provides_an_answer |
|
|
So, 24 male generations are about 800 years, and 20 male generations about 667 years |

Years per Generation: tracing McAninch birth dates over the 19 generations (6 + 6 + 7), |
|
|
the McAninch average was 32.3 years/generation (close to 33, and much greater than 25) |

Years Before Present (‘ybp’) is a time scale used mainly in geology and other scientific |
|
|
disciplines to specify when events in the past occurred. Since our "present" is variable, |
|
|
standard practice uses 1 January 1950 as the beginning date of the ‘YBP’ age scale, |
|
|
reflecting the fact that radiocarbon dating became practicable in the 1950s. |

TMRCA (3): 20 generations: 95.37% - 97.61% (96.5% mean, range ~2.2%); estimate |
|
|
(3 generations / 100 years), 667 ybp (1950), +/- 100 years (15%), range 1180-1385 CE |
|
[59] |
TMRCA (3): 24 generations: 98.53% - 99.42% (98.9% mean, range ~0.9%); estimate |
|
|
(3 generations / 100 years), 800 ybp (1950), +/- 120 years (15%), range 1030-1270 CE |
