text: This comes up a lot during genetic genealogy, since when I look at the family tree of a DNA match, I am usually looking for common ancestors, and especially our most recent common ancestor (MRCA), which will help me figure out our exact relationship.
text: Such time to most recent common ancestor (TMRCA) estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non-genetic, mathematical model or computer simulation.
text: Our most recent common ancestors (MRCA) are my great-great-great grandparents born about 1860 (they were her grandparents).
text: Y-DNA testing results are normally stated as probabilities: For example, with the same surname a perfect 37/37 marker test match gives a 95% likelihood of the most recent common ancestor (MRCA) being within 8 generations, while a 111 of 111 marker match gives the same 95% likelihood of the MRCA being within only 5 generations back.
