متن کاملDiscrimiantion analysis of hybrid Pangasianodon hypophthalmus (Sauvage, 1983) (♀) × Pangasius nasutus (♂) (Bleeker, 1976) and its parental species
Comparative analysis was performed to discriminate a hybrid produced from the crossbreed of Pangasianodon hypophthalmus (♀) and Pangasius nasutus (♂) and its parental species based on morphology appearances and morphometric characters. Morphological structures of the vomerin and palatal teeth varied between the hybrid and both parents. Results of the univariate analysis revealed 22 morphometric...
متن کاملGenome expansion in three hybrid sunflower species is associated with retrotransposon proliferation
The origin of new diploid species through inter-specific hybridization may be facilitated by rapid genomic reorganization. There is evidence that this process was involved in the independent origins of three annual sunflower species in the genus Helianthus. The three hybrid taxa, H. anomalus, H. deserticola and H. paradoxus, are products of ancient hybridization events between the same two pare...
متن کاملHomoploid hybrid speciation and genome evolution via chromosome sorting.
Genomes of numerous diploid plant and animal species possess traces of interspecific crosses, and many researches consider them as support for homoploid hybrid speciation (HHS), a process by which a new reproductively isolated species arises through hybridization and combination of parts of the parental genomes, but without an increase in ploidy. However, convincing evidence for a creative role...
متن کاملReproductive Isolation of Hybrid Populations Driven by Genetic Incompatibilities
Despite its role in homogenizing populations, hybridization has also been proposed as a means to generate new species. The conceptual basis for this idea is that hybridization can result in novel phenotypes through recombination between the parental genomes, allowing a hybrid population to occupy ecological niches unavailable to parental species. Here we present an alternative model of the evol...
