Should the values of pairwise genetic distances and Fst be somewhat similar?

Question

[akang]

I have used an R package called Adegenet to calculate pairwise Fst and pairwise genetic distances from an alignment file. But both the values are completely different.

matFst <- pairwise.fst(mydata,res.type="matrix") #pairwise Fst
temp <- pairDistPlot(mydata, other(mydata)$pop) # pairwise genetic distance

Example, my maximum pairwise genetic distance between two populations is 7% whereas Maximum Fst is 80%. Can somebody explain me more on that? TIA
