Phylogeny and phylogeography of the Liolaemus darwinii complex (Squamata: Liolaemidae): Evidence for introgression and incomplete lineage sorting
(Society for the Study of Evolution, 2004-04)
Although mitochondrial DNA markers have several properties that make them suitable for phylogeographic studies, they are not free of difficulties. Phylogeographic inferences within and between closely related species can ...
Male-mediated introgression of Bos indicus genes into Argentine and Bolivian Creole cattle breeds
(Wiley Blackwell Publishing, Inc, 2000-10)
The geographic distribution and frequency of Bos taurus and Bos indicus Y chromosome haplotypes amongst Argentine and Bolivian Creole cattle breeds were studied, using cytogenetic and molecular genetic techniques. A complete ...
Introgression of cultivated sunflower in exotic Helianthus petiolaris populations
(Sociedad Argentina de Genetica, 2012-12)
Cultivated sunflower Helianthus annuus and the wild exotic H. petiolaris are sympatric species in an extensive region of central Argentina. Both species are sexually compatible, they overlap their flowering time and share ...
Neanderthal introgression in SCN9A impacts mechanical pain sensitivity
(Nature Research, 2023)
The Nav1.7 voltage-gated sodium channel plays a key role in nociception. Three functional variants in the SCN9A gene (encoding M932L, V991L, and D1908G in Nav1.7), have recently been identified as stemming from Neanderthal ...
Rapid radiation and rampant reticulation: Phylogenomics of South American Liolaemus lizards
(Oxford University Press, 2021-07)
Understanding the factors that cause heterogeneity among gene trees can increase the accuracy of species trees. Discordant signals across the genome are commonly produced by incomplete lineage sorting (ILS) and introgression, ...
Phenotypic selection under two contrasting environments in wild sunflower and its crop‐wild hybrid
(Wiley Blackwell Publishing, Inc, 2019-06-05)
Hybridization is a common phenomenon in plants and can lead to the introgression of alleles from one population into another, generate new hybrid lineages, or cause species extinction. The environmental conditions and the ...
Phylogenetic relationships and intraspecific diversity of a North Patagonian Fescue: evidence of differentiation and interspecific introgression at peripheral populations
(2018-03)
Peripheral sites usually offer suboptimal conditions for species with wide distributions, where expression of phenotypic variability and potential interspecific hybridization might be enhanced. The Patagonian steppe, the ...
Evidence of hybridization, mitochondrial introgression and biparental inheritance of the kdna minicircles in trypanosoma cruzi i
(Public Library of Science, 2020-01)
Background Genetic exchange in Trypanosoma cruzi is controversial not only in relation to its frequency, but also to its mechanism. Parasexual genetic exchange has been proposed based on laboratory hybrids, but population ...
Automatic landmarking identifies new loci associated with face morphology and implicates Neanderthal introgression in human nasal shape
(Nature Research, 2023)
We report a genome-wide association study of facial features in >6000 Latin Americans based on automatic landmarking of 2D portraits and testing for association with inter-landmark distances. We detected significant ...
