Summary of results from BOTTLENECK for six Naja atra populations for the Wilcoxon's test for both the two-phase model (TPM) and stepwise mutation model (SMM) along with results from the mode-shift test.

Under the mode-shift test, an L-shaped distribution of alleles is expected in the absence of a bottleneck whereas a distribution with a shifted mode is expected in a population that has gone through a bottleneck. See Table 1 for sample site abbreviations.在众数偏移检验（mode-shift test）中，未经历种群瓶颈的种群，其等位基因（allele）分布预期呈L形；经历过种群瓶颈的种群，其等位基因分布则会呈现众数偏移的形态。样本位点缩写详见表1。
