Interpretation

There is great geographical differentiation among the populations in the frequency of the Standard chromosome arrangement ( $F_{IT} =
0.2160$, but $F_{ID} = 0.0444$).

Most of this geographical differentiation is a result of differences among the four primary subdivisions ( $F_{ST} = 0.1478$). Relatively minor differentiation is found among regions within a given subdivision ( $F_{RS} = 0.0373$) and among demes within a region ( $F_{DR} = 0.0444$).

Thus, an explanation for the chromosomal diversity that predicted great local differentiation and little or no differentiation at a large scale would be inconsistent with these observations.
