WebIn the case of humans, the genetic diversity decreases essentially linearly with increasing geographic distance from Africa [2, 3], which is indicative of the human mi-gration out of Africa. It is hoped [9], that the observed patterns of neutral genetic diversity can be used to infer details of the corresponding colonization pathways. WebAllele surfing, a hallmark of spatial growth, has been shown to give rise to a different probability distribution characterized by an excess of mutational jackpot events . Here, we have shown that, while allele surfing can explain the behavior of large clones, it fails to describe the majority of mutations that reach much lower frequencies. raiffeisen bank merhemića trg sarajevo
