Meiotic drive shapes rates of karyotype evolution in mammals. [PDF]
Evolution, 2019 Chromosome number is perhaps the most basic characteristic of a genome, yet generalizations that can explain the evolution of this trait across large clades have remained elusive.

Impact of Chromosomal Rearrangements on the Interpretation of Lupin Karyotype Evolution. [PDF]
Genes (Basel), 2019 Plant genome evolution can be very complex and challenging to describe, even within a genus. Mechanisms that underlie genome variation are complex and can include whole-genome duplications, gene duplication and/or loss, and, importantly, multiple ...

Shifts in Chromosome Evolution Rates Shape the Karyotype Patterns of Leafcutting Ants
Ecology and EvolutionTrait evolution has become a central focus in evolutionary biology, with phylogenetic comparative methods offering a framework to study how and why traits vary among species. Identifying variations in trait evolution rates within phylogenies is important

Reconstruction of ancestral karyotype illuminates chromosome evolution in the genus Cucumis
Plant Journal, 2021 Karyotype dynamics driven by complex chromosome rearrangements constitute a fundamental issue in evolutionary genetics. The evolutionary events underlying karyotype diversity within plant genera, however, have rarely been reconstructed from a computed ...

Karyotype evolution and speciation in Orthoptera
Journal of Evolutionary BiologyAbstract Karyotype evolution might fuel speciation and can thereby contribute to species diversity. To test the hypothesis that speciation and karyotype change are linked, we estimated anagenetic and cladogenetic rates of karyotype evolution as well as speciation rates in Orthoptera. We compiled the male diploid chromosome number and the

Karyotype evolution supports the molecular phylogeny in the genus Ranunculus (Ranunculaceae)
Perspectives in Plant Ecology, Evolution and Systematics, 2016 Karyotype evolution can be reconstructed by the characterization of chromosome morphology, based on the position of centromeres. Different karyotypes often reflect speciation events within phylogenies as they can establish crossing barriers between ...

Karyotype differentiation in the Nothobranchius ugandensis species group (Teleostei, Cyprinodontiformes), seasonal fishes from the east African inland plateau, in the context of phylogeny and biogeography [PDF]
Comparative Cytogenetics, 2023 The karyotype differentiation of the twelve known members of the Nothobranchius ugandensis Wildekamp, 1994 species group is reviewed and the karyotype composition of seven of its species is described herein for the first time using a conventional ...
