Various commonly used algorithms/analyses for ancestry inference are applied to dissect the ancestry composition and genetic affinity of an individual of interest.
Ancestry composition. To determine the global (genome-wide) ancestry composition of an individual based on ADMIXTURE analysis. A summary plot of the genetic admixture is provided. Each individual is represented by a single line broken into K-colored segments, with lengths proportional to the K inferred components (Cs). The population IDs are presented outside of the circle of the plot.
Archaic ancestry. To estimate the archaic ancestry of an individual, in the current version, archaic ancestry mainly refers to that of Neanderthal and Denisovan.
Uniparental lineages.To determine the haplogroups of mtDNA and/or chromosome Y of an individual. A map is provided with a human migration route based on Y or mtDNA haplogroup to illuminate the possible genetic history of the individual studied.
Regional affinity. To estimate the genetic relationship of the sample with genetic substructure populations, i.e., to determine the most likely genetic substructure populations from which the individual is.
