Chromosomes and speciation in tuco-tuco (Ctenomys, Hystricognathi, Rodentia)Хромосомы и видообразование у туко-туко (Ctenomys, Hystricognathi, Rodentia)
(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2016-09)
Tuco-tucos, South American rodents of the genus Ctenomys represent an interesting model of speciation. Their strict territorial and solitary life under the earth, vast but highly fragmented habitats, low migration activity ...
110 Years of orthopteran cytogenetics, the chromosomal evolutionary viewpoint, and Michael White's signal contributions to the field
(Pensoft Publishers, 2010-12)
The history of the study of orthopteran chromosomes is coincident with the formulation of the chromosome theory of heredity and the rediscovery of Mendel's laws, thus with the birth of cytogenetics. We review the early ...
Insights into the karyotype evolution and speciation of the beetle Euchroma gigantea (Coleoptera: Buprestidae)
(2018-09-01)
Euchroma Dejean, 1833 (Buprestidae: Coleoptera) is a monotypic genus comprising the species Euchroma gigantea, with populations presenting a degree of karyotypic variation/polymorphism rarely found within a single taxonomic ...
Empirical demonstration of hybrid chromosomal races in house mice
(Society for the Study of Evolution, 2016-06-11)
Western house mice (Mus musculus domesticus) and common shrews (Sorex araneus) are important models for study of chromosomal speciation. Both had ancestral karyotypes consisting of telocentric chromosomes, and each is ...
Genetic differentiation within and away from the chromosomal rearrangements characterising hybridising chromosomal races of the western house mouse (Mus musculus domesticus)
(Springer, 2016-05)
The importance of chromosomal rearrangements for speciation can be inferred from studies of genetic exchange between hybridising chromosomal races within species. Reduced fertility or recombination suppression in karyotypic ...
Genetic differentiation within and away from the chromosomal rearrangements characterising hybridising chromosomal races of the western house mouse (Mus musculus domesticus)
(Springer, 2016-04-05)
The importance of chromosomal rearrangements for speciation can be inferred from studies of genetic exchange between hybridising chromosomal races within species. Reduced fertility or recombination suppression in karyotypic ...
Population differentiation and speciation in the genus Characidium (Characiformes: Crenuchidae): effects of reproductive and chromosomal barriers
(Wiley-Blackwell, 2014-03-01)
Both time and low gene flow are the key factors by which different biological species arise. The divergence process among lineages and the development of pre- or postzygotic isolation occur when gene flow events are lacking. ...
Chromosome synapsis and recombination in simple and complex chromosomal heterozygotes of tuco-tuco (Ctenomys talarum: Rodentia: Ctenomyidae)
(Springer, 2014-06)
The chromosomal speciation hypothesis suggests that irregularities in synapsis, recombination, and segregation in heterozygotes for chromosome rearrangements may restrict gene flow between karyotypically distinct populations ...
Chromosome painting of Z and W sex chromosomes in Characidium (Characiformes, Crenuchidae)
(2013-01-24)
Some species of the genus Characidium have heteromorphic ZZ/ZW sex chromosomes with a totally heterochromatic W chromosome. Methods for chromosome microdissection associated with chromosome painting have become important ...
