Pollinator-Mediated Isolation May Be an Underestimated Factor in Promoting Homoploid Hybrid Speciation
It is widely acknowledged that allopolyploidy via hybridization and genome doubling can easily lead to speciation, as polyploid hybrids can be immediately isolated from diploid parental taxa due to high levels of sterility caused by uneven numbers of chromosome complements in their progeny (Soltis and Soltis, 2009; Abbott et al., 2013). However, homoploid hybrid speciation (HHS), in which a hyb...
متن کاملHomoploid hybrid speciation in action
Homoploid hybrid speciation is the origin of a hybrid species without change in chromosome number. Although currently thought to be a rare form of speciation, especially relative to the more common allopolyploid hybrid speciation, it is feasible that many examples of homoploid hybrid species will be discovered in the future now that genetic resources are readily available for testing their occu...
متن کاملHomoploid hybrid speciation in animals.
Among animals, evidence for homoploid hybrid speciation (HHS, i.e. the creation of a hybrid lineage without a change in chromosome number) was limited until recently to the virgin chub, Gila seminuda, and some controversial data in support of hybrid status for the red wolf, Canis rufus. This scarcity of evidence, together with pessimistic attitudes among zoologists about the evolutionary import...
متن کاملHomoploid hybrid speciation in an extreme habitat.
According to theory, homoploid hybrid speciation, which is hybrid speciation without a change in chromosome number, is facilitated by adaptation to a novel or extreme habitat. Using molecular and ecological data, we found that the alpine-adapted butterflies in the genus Lycaeides are the product of hybrid speciation. The alpine populations possess a mosaic genome derived from both L. melissa an...
متن کاملHow common is homoploid hybrid speciation?
Hybridization has long been considered a process that prevents divergence between species. In contrast to this historical view, an increasing number of empirical studies claim to show evidence for hybrid speciation without a ploidy change. However, the importance of hybridization as a route to speciation is poorly understood, and many claims have been made with insufficient evidence that hybrid...
