The chromosomal constitution of fish hybrid lineage revealed by 5S rDNA FISH. [PDF]
BMC Genet, 2015 The establishment of the bisexual fertile fish hybrid lineage including the allodiploid and allotetraploid hybrids, from interspecific hybridization of red crucian carp (Carassius auratus red var. 2n = 100, 2n = AA) (♀) × common carp (Cyprinus carpio L.

DNA hybridization evidence for the principal lineages of hummingbirds (Aves:Trochilidae) [PDF]
Molecular Biology and Evolution, 1997 The spectacular evolutionary radiation of hummingbirds (Trochilidae) has served as a model system for many biological studies. To begin to provide a historical context for these investigations, we generated a complete matrix of DNA hybridization distances among 26 hummingbirds and an outgroup swift (Chaetura pelagica) to determine the principal ...

Beyond clines: lineages and haplotype blocks in hybrid zones [PDF]
Molecular Ecology, 2016 Abstract Hybrid zones formed between recently diverged populations offer an opportunity to study the mechanisms underlying reproductive isolation and the process of speciation. Here, we use a combination of analytical theory and explicit forward simulations to describe how selection against hybrid genotypes ...

Repeated Reticulate Evolution in North American Papilio machaon Group Swallowtail Butterflies. [PDF]
PLoS ONE, 2015 Hybridization between distinct populations or species is increasingly recognized as an important process for generating biodiversity. However, the interaction between hybridization and speciation is complex, and the diverse evolutionary outcomes of ...

Caryologia, 2021 A conventional cytogenetics analysis revealed for first time an allopolyploid lineage of the genus Aeschynomene in Mexico. The hybrid condition is confirmed after all the prometaphase and metaphase nuclei of the hybrids exhibited only one pair of SAT ...

Parsimonious Inference of Hybridization in the Presence of Incomplete Lineage Sorting [PDF]
Systematic Biology, 2013 Hybridization plays an important evolutionary role in several groups of organisms. A phylogenetic approach to detect hybridization entails sequencing multiple loci across the genomes of a group of species of interest, reconstructing their gene trees, and taking their differences as indicators of hybridization. However, methods that follow this approach

Disentangling Population History and Character Evolution among Hybridizing Lineages [PDF]
Molecular Biology and Evolution, 2020 AbstractUnderstanding the origin and maintenance of adaptive phenotypic novelty is a central goal of evolutionary biology. However, both hybridization and incomplete lineage sorting can lead to genealogical discordance between the regions of the genome underlying adaptive traits and the remainder of the genome, decoupling inferences about character ...

Using supernetworks to distinguish hybridization from lineage-sorting [PDF]
BMC Evolutionary Biology, 2008 A simple and widely used approach for detecting hybridization in phylogenies is to reconstruct gene trees from independent gene loci, and to look for gene tree incongruence. However, this approach may be confounded by factors such as poor taxon-sampling and/or incomplete lineage-sorting.Using coalescent simulations, we investigated the potential of ...

PHYLOGENETIC EVIDENCE FOR HYBRID ORIGINS OF ASEXUAL LINEAGES IN AN APHID SPECIES [PDF]
Evolution, 2003 Understanding the mode of origin of asexuality is central to ongoing debates concerning the evolution and maintenance of sexual reproduction in eukaryotes. This is because it has profound consequences for patterns of genetic diversity and ecological adaptability of asexual lineages, hence on the outcome of competition with sexual relatives both in ...

The ascomycete Verticillium longisporum is a hybrid and a plant pathogen with an expanded host range. [PDF]
PLoS ONE, 2011 Hybridization plays a central role in plant evolution, but its overall importance in fungi is unknown. New plant pathogens are thought to arise by hybridization between formerly separated fungal species.
