Particularly, the dynamics are notably different when the ancient samples are directly ancestral to the present-day samples and when they belong to a sister population that diverged from the present-day population.
Besides, Ht1 and Ht2 were the most frequent lineages in our present day sample set (Ht1: 16.5% and Ht2: 27.8%) as well as in the data published by Pakendorf et al [ 6] (Ht1: 43% and Ht2: 10%).
Furthermore, the demographic changes occurring in the Yakut population since the Russian colonization make it difficult to reconstruct the genetic history using present day samples.
Given an admixed population PC derived from two ancestral populations PA and PB, the number of individuals in the analysis (i.e., present day samples) is n = nA = nB + nC.
The process starts from the present-day sample and proceeds backward in time, allowing a succession of coalescent and recombination events to shape the genealogy.
Indeed, most of the sequences present in our ancient sample (83%) have been transmitted to the present day population.
The samples were collected in the period 1989 1993 and the ethical procedures followed the present day standard.
Her influence continues to the present day.
