WebUnderstanding the genetic consequences of changes in species distributions has wide-ranging implications for predicting future outcomes of climate change, for protecting threatened or endangered populations and for understanding the history that has led to current genetic patterns within species. ... genetic recovery time and allele surfing. We ... 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.
