Web1 nov 2024 · Tajima' D is very useful to investigate the nucleotide sequence is under mutation-drift equilibrium. A negative value of Tajima's D indicated the population size … WebA positive Tajima's D signifies low levels of both low and high frequency polymorphisms, indicating a decrease in population size and/or balancing selection. However, calculating a conventional "p-value" associated with any Tajima's D value that is obtained from a sample is impossible. Briefly, this is because there is no way to describe the ...

Web9 dic 2013 · The Tajima’s D test is based on comparison of the allelic frequency of segregating nucleotide sites. A positive value of this test indicates a bias towards intermediate frequency alleles, negative value indicates a bias towards excess of the number of rare alleles and the latter being a signature of recent population expansion.
