Sentence examples for hybridization population from inspiring English sources

Crucial processes such as hybridization, population fragmentation and increased genetic drift may occur more often at the margins than in the core of a species' range [ 1– 3].

As described below, the analysis of these data was used to characterize the spectral and dynamic signatures of false hybridization populations.

Some issues, such as the lack of knowledge about adaptive potential in the hybridized population before hybridization, may be difficult to address.

This is consistent with the results of a previous study, in which we used the same N10 populations to study the long-term effects of hybridization on population fitness: we found significant heterosis in populations crossed at intermediate, but not in populations crossed at high inbreeding level (Pekkala et al. 2012a).

We performed a phylogeographic analysis using the Neighbor-net method (Bryant and Moulton 2004) implemented in SplitsTree4 (Huson and Bryant 2006) based on the pairwise FST between populations to reveal more details of the evolutionary relationship between populations, for example, hybridization between populations.

Such an observation might be viewed as evidence that selection removes maladaptive alleles following hybridization, returning population fitness to levels more like closely related nonstocked populations.

There is one RFLP map of diploid peanut developed from the interspecific hybridization (F2 population) of two related diploid species with AA genome (A. stenosperma and A. cardenasii) of peanut with 11 linkage groups [ 11].

Further detailed investigation of genomic clines and hybrid fitness along the hybrid zones at the margins of the ranges would provide insights into the roles of hybridization in population persistence and expansion in a changing environment.

Our study illustrates that the relative frequency of the two species strongly determines the effectiveness of reproductive barriers and that even the more choosy species (Ch. montanus) may face a higher risk of hybridization if population size decreases and its relative frequency becomes low compared to its sister species.

Hybridization between populations or species can have either beneficial or detrimental effects on fitness.

Future work should also extend the approach to address crops with more complex trajectories, involving multiple origins and hybridization between populations domesticated in different areas, which would require further methodological development.
