Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become reproductively isolated for some period of time, as there is not any genetic exchange ...

7.5 Genetic divergence Perhaps the most striking evidence of speciation is genome divergence. It results from mutations, recombination, or neutral processes such as genetic drift. Genetic divergence is estimated using relative divergence (i.e., FST and related measures), absolute divergence (d xy), and several other metrics (reviewed in [176]).

Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes through time, often after the populations have …

Far too often, phenotypic divergence has been misinterpreted as genetic divergence, and based on phenotypic divergence, genetic divergence has been indicated. We have attempted to disprove this statement and call for the differentiation of phenotypic and genotypic variation.

We begin by laying out the metaphoric foundation on which the study of genomic architecture is currently based, introducing the concept of ‘genomic islands of divergence’ and the processes generating such divergence (see table 1 for definitions).

Molecular genetic data can provide information on the levels and distribution of genetic variability within and between populations, influence of mating patterns, relative roles of microevolutionary forces, and patterns of colonization and time since divergence.

2023年12月20日 · One of the key implications of genetic isolation is the divergence of genetic traits between different populations. When a population is isolated, the genetic variations that arise through processes such as mutation and recombination become distinct from the genetic makeup of other populations.

This transparent and computationally efficient approach to infer population divergence time makes it possible to estimate time scaled in generations (assuming a mutation rate), and not as a compound parameter of genetic drift.

4 天之前 · Describing the distribution of genetic variation across individuals is a fundamental goal of population genetics. We present a method that capitalizes on the rich genealogical information encoded in genomic tree sequences to infer the geographic locations of the shared ancestors of a sample of sequenced individuals. We used this method to infer the geographic history of …

Although the description of patterns of genomic divergence seems straightforward, the papers in this issue highlight the difficulties we still face in accurately resolving genome-wide patterns of genetic differentiation and interpreting their meaning.
