On the measurements of genetic differentiation among populations

WebFST can be used, for example, to test whether there is evidence of low gene flow between populations. In the case of the fire ant, the B and b supergene variants coexist in the population, but do not recombine with each other - so they should show strong differentiation. An important population genetics measure is genetic diversity. WebI reexamine the use of isolation by distance models as a basis for the estimation of demographic parameters from measures of population subdivision. To that aim, I first provide results for values of F-statistics in one-dimensional models and coalescence times in two-dimensional models, and make mor … dick\u0027s sporting goods senior discount
