Web1 dic 2024 · Tajima's D values less than 0 indicate purifying selection, while values greater than 0 indicate balancing selection [20].Overall, both core genomes for X. euvesicatoria and X. perforans trended towards purifying selection. The average Tajima's D value for X. euvesicatoria was −2.15 with a standard deviation of 0.61 (Fig. 1 a), while the average … WebThe Tajima's D and Fu's Fs tests were performed based on COI and D-loop sequences to detect the population expansion of U. unicinctus. For all samples, both of COI and D-loop neutrality test showed significantly negative Tajima's D …
WebAnalysis of Perlegen data: To illustrate the use of the correction of Tajima's D, we applied it to a Perlegen data set (Hinds et al. 2005), previously analyzed by Clark et al. (2005)D values. An example of the result, using windows of 500 kb on chromosome 1, is shown in Figure 4.

WebA negative Tajima's D value is usually interpreted as purifying selection, or as a signature of a recent population expansion. You didn't explain how you calculated the p-value, so it is difficult to interpret it. It seems that it is higher than 0.10, so not significant. You should plot the distribution of Tajima's D on the rest of the genome ...
