Significance Test for Fst Values

Question

[kacollier]

Hello,

I am looking at divergence in two populations of birds (one North American and one Eurasian), using full mitogenomes and a sample size of ~10 per population. Prior to downstream analysis, I would like to see if their fst values are significantly different from each other. Does anyone know if there's an R script or program somewhere that would calculate those values and/or perform a significance test?

Thanks in advance for your time.
