WebHybridization is referred to a process through which there is interbreeding between species of two genetically distinct populations or species. Introgression is a genetic crossover that takes place between the species of the same population via a backcross to one or both of the parent species.

WebIntrogressive hybridization, or introgression, refers to the process of interspecific genetic transfer by means of backcrossing. Backcrossing is the process of a hybrid species crossing with one of the parent species of the hybrid (Figure 1). Introgression creates variety within the gene pool of a species, facilitating adaptive radiation that allows organisms to fulfill … WebWhat is introgression in fish?

WebOct 11, 2024 · Introduction. Interbreeding between partially diverged species or subspecies can result in admixed individuals with low fitness, e.g. due to hybrid incompatibilities [1–3].Consistent with the view that hybridization is often deleterious, a growing number of species show evidence of pervasive selection against introgressed ancestry [4–13]. WebAcross much of the globe, fire is a major disturbance agent of forest and grassland communities. The removal of fire from previously fire-maintained ecosystems, which has occurred in many areas, changes species composition, favoring later less fire tolerant species over fire-adapted ones.
