Ewens and Watterson is a test of neutrality. Bold numerals indicate p-values less than 0.05 indicating that a particular haplotype was identified in the ecotype more frequently than the expectation. This test returned Not applicable (NA) when only one haplotype is identified in the sample. Fu’s Fs statistic is a measure of a population expansion based on population genetics. Bold numerals indicate p-values less than 0.05, hence a significant evidence for a population expansion.
