WebDec 16, 2014 · We found very little introgression between B. nana and B. pendula, despite both being diploid, perhaps because their distributions in the past have rarely overlapped. Future conservation of B. nana may partly depend on minimization of hybridization with B. pubescens, and avoidance of planting B. pendula near B. nana populations. Show less 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].
WebA high introgression level (36.4%) in the Bizerta lagoon and much less outside indicate that this is the main area where hybridization occurs while introgression clines towards the south in S. aegyptiaca and towards the north in S. senegalensis plead in favour of the existence of a unimodal hybrid zone. WebDec 31, 2014 · It is concluded that gene flow caused by natural hybridization in Ligularia indeed plays an important role in the species diversity and varying degrees of hybridization and introgression occur differently depending on the habitat context. Natural hybridization has been considered to represent an important factor influencing the high diversity of the …
