Summary
| Description |
English: The patterns of isolation by distance as shown among human genetic data representing 346 microsatellite loci taken from 1484 individuals in 78 human populations. The horizontal axis of both charts is geographic distance as measured along likely routes of human migration. The upper graph illustrates that as populations are further from East Africa (represented by the city of Addis Ababa), they have declining genetic diversity as measured in average number of microsatellite repeats at each of the loci. The bottom chart measures the genetic distance between all pairs of populations according to the Fst statistic; populations with a greater distance between them are more dissimilar than those which are geographically close to one another. This chart appeared as part of a study demonstrating how computer-simulated migration can replicate the empirical data.

The left half of Figure 1 (i.e., Figure 1A) from Kanitz R, Guillot EG, Antoniazza S, Neuenschwander S, Goudet J (2018) Complex genetic patterns in human arise from a simple range-expansion model over continental landmasses. PLoS ONE 13(2): e0192460. https://doi.org/10.1371/journal.pone.0192460 "Data from this study represent a subset of the dataset originally made available by Pemberton et al. [23], Rosenberg et al. [3] and Wang et al. [22]. Since we used a strict mutation model, we chose 346 microsatellite loci whose length is proportional to the repeated segment length. These loci represent the ones termed ‘regular’ by Pemberton et al. [23] that are also available in the Wang et al [22] dataset. The number of populations in the original dataset was 78, totaling 1484 individuals distributed throughout the world."
