22 Αυγ 2014 · Cite. Permissions. Share. Species can be defined as populations that are diagnosably distinct, reproductively isolated, cohesive, or exclusive groups of organisms. Boundaries between species in sympatry are maintained by intrinsic barriers to gene exchange; these boundaries may not be uniform in space, in time, or across the genome.
17 Μαρ 2016 · Hybridization is particularly common among oak species, where it may spread or generate adaptive genetic variation and where it has been proposed as a key component of natural and human-induced invasions (Petit et al. 2004; Moran et al. 2012 ).
Gene flow is important in a remarkable variety of applied situations. This Special Issue presents some representative points in the galaxy of applied topics in which gene flow plays a key role. The number of possible topics precludes an exhaustive treatment.
28 Νοε 2016 · With the growing availability of genomic tools and advancements in genomic analyses, it is becoming increasingly clear that gene flow between divergent taxa can generate new phenotypic diversity, allow for adaptation to novel environments, and contribute to speciation.
Hybridization is particularly common among oak species, where it may spread or generate adaptive genetic variation and where it has been proposed as a key component of natural and human‐induced invasions (Petit et al. 2004; Moran et al. 2012).
7 Σεπ 2011 · Hybridization, the crossbreeding between individuals of different species, and introgression, the transfer of genes between species mediated primarily by backcrossing, have been the focus of...
