Sentence examples for genetic sectors from inspiring English sources

We were particularly interested in the biogeographic context and the demographic processes contributing to the formation and integrity of stable genetic sectors in NW Iberian F. ceranoides.

A pattern of approximate stepping stone expansions originating in different refugia could promote the formation of genetic sectors even in the absence of dispersal barriers.

Currently there are no large, estuarine-free regions along this shoreline and therefore distance per se cannot be invoked as a major contemporary factor accounting for the much deeper genomic differentiation among than within NW Iberian genetic sectors.

The contemporary genetic sectors in Iberian F. ceranoides are more likely to result from the regional reassembly of vicariant phylogroups into their current distributions following a period of independent, mostly allopatric divergence in past contracted areas of occurrence.

The Iberian peninsula is a good example where diverse taxa such as trees [ 34], amphibians [ 35, 36], reptiles [ 37, 38] and pond-dwelling invertebrates [ 39, 40] are sub-divided into well defined, mostly parapatric genetic sectors that presumably formed during expansions from disjunct refugia.

The deep divergence between sectors coupled with the lack of support for a role of oceanographic barriers in defining the location of breaks suggested 1) that the parapatric genetic sectors result from the regional reassembly of formerly vicariant sub-populations, and 2) that the genetic discontinuities at secondary contact zones (and elsewhere) are maintained despite normal migration rates.

Estimates based on quantitative analyses suggest that these genetically discordant sectors are very small but can have a complex genetic makeup.

In developing dairy sectors, genetic improvement programs have limited resources and recording of herds is minimal.

We used spatially explicit analysis to detect gradients in observed genetic diversity or sectors of low genetic diversity in response to late Quaternary climate oscillations.

Beef cattle and sheep methane emissions were reduced by less than 1% during the same period, attributed to the slower adoption of genetic evaluation in these sectors.

In addition, AMOVA was conducted to estimate genetic variation among latitudinal sectors and a linear regression was tested against latitude using SigmaPlot, version 10.0, considering He and PPB as dependent variables.
