Pedigree Comparisons

Here are results of using Nordtvedt's spreadsheet Generations111T.xlsx to estimate coalescence age and TMRCA of a clade are compared to the corresponding ages from sets of known pedigrees and their most recent common ancestor.

  • Ave = Average of all pairwise TMRCA in the set of haplotypes
  • Max = Maximum of all pairwise TMRCA in the set of haplotypes
  • GA coal = GA coal is coalescence age or AVE estimate for clade A
  • GA = TMRCA estimate fo founder of the clade A
  • SigGA = Standard deviation for GA

YFULL Comparisons

Here are results of using Nordtvedt's spreadsheet Generations111T.xlsx to estimate the TMRCA of a clade are compared to the corresponding SNP based TMRCA in the YFULL tree. Those labeled surnames are small sets of haplotypes identical with those used in the YFULL tree. For those labeled haplogroups, the set of haplotypes in the YFULL data is unknown so a large number of haplotypes is used from data in the corresponding haplogroup project.
