Number of y-chromosome markers:
Based on the
Infinite Alleles Model
. Note that this model underestimates the time to MRCA. This is relatively insignificant as sample markers increase beyond 25, but can be significant with fewer markers.
Average Mutation Rate:
Please enter the number of markers and the mutation rate. Current studies suggest a mutation rate of
. Results will include up to 5 mismatches. More mismatches than this are probably not useful for most genealogical purposes.
