Karyological Characterization of the Endemic Iberian Rock Lizard, Iberolacerta Monticola (Squamata, Lacertidae): Insights into Sex Chromosome Evolution [PDF]

, 2013
[Abstract] Rock lizards of the genus Iberolacerta constitute a promising model to examine the process of sex chromosome evolution, as these closely related taxa exhibit remarkable diversity in the degree of sex chromosome differentiation with no clear ...

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Microevolutionary differentiation of cereal tetraploid species by formation of recombinant genomes

Вавиловский журнал генетики и селекции, 2016
The process of microevolutionary differentiation of cereals by formation of recombinant genomes was studied in dynamics (F6–F17) with tetraploid wheat-rye amphidiploids as examples. Evidence that joint growing of tetra ploid amphidiploids having a common

Cytogenetic description of Bunocephalus doriae Boulenger, 1902 (Siluriformes: Aspredinidae) from the Paraná River (Misiones, Argentina)

Neotropical Ichthyology
In this work, Bunocephalus doriae was cytogenetically analyzed. A karyotype with a diploid number of 2n= 50 comprising 6m, 10sm, 6st, and 28a (FN= 72) chromosomes was observed.

Alien introgressions and chromosomal rearrangements do not affect the activity of gliadin-coding genes in hybrid lines of Triticum aestivum L. × Aegilops columnaris Zhuk

Вавиловский журнал генетики и селекции, 2018
Using chromosome C-banding and electrophoresis of grain storage proteins, gliadins, 17 Triticum aestivumAegilops columnaris lines with substitutions of chromosomes of homoeologous groups 1 and 6 were examined.

The significance of cytogenetics for the study of karyotype evolution and taxonomy of water bugs (Heteroptera, Belostomatidae) native to Argentina [PDF]

, 2013
Male meiosis behaviour and heterochromatin characterization of three big water bug species were studied. Belostoma dentatum (Mayr, 1863), B. elongatum Montandon, 1908 and B. gestroi Montandon, 1903 possess 2n = 26 + X1X2Y (male).

Multiple supernumerary chromosomes in the pseudogamous parthenogenetic flatworm Polycelis nigra:lineage markers or remnants of genetic leakage? [PDF]

, 1997
Polycelis nigra is a free-living simultaneous hermaphroditic flatworm that has amphimictic and pseudogamous parthenogenetic biotypes. Sexual individuals are always diploid (2n = 16) and pseudogamous parthenogens are polyploid (usually triploid).
