Interpretation of Theta k, Theta S and Theta pi

Question

[hannileinklein]

Hi everyone,

I calculated three different Theta values (k, S and pi) for my haploid data set in Arlequin. The data set consists of 346 samples from 22 populations. The underlying alignment is a SNP matrix with a length of 113 bp. I have over all high values (>0.5) for gene diversity H and very low values (<0.07) for nucleotide diversity P. Values for the mean number of pairwise differences range from 0.5 to 7.5. Unfortunately, I failed to interpret the resulting values for Theta. Can someone please explain to me how to bring them in context with the other results? Is there a common way to interpret these values?

Thank you very much in advance and stay healthy! Best, Johanna
