Constitutive-heterochromatin placement in the genome affects chromosome structure by occupying centromeric areas and forming large blocks. (bvsalud.org)
Deer3
The acrocentric type is found in three independent deer lineages (subfamily Cervinae and in two Capreolinae tribes-Odocoileini and Capreolini). (bvsalud.org)
Deer family is one of the most abundant mammalian families in the world. (chinagene.cn)
It is currently well accepted that deer is a very valuable model for the studies of ecology, behavior, evolution and biology, especially for the study of mammalian organ regeneration. (chinagene.cn)
Comparative2
We carried out comparative analyses of chromosome evolution in the congeneric species I. galani and I. bonnali, as well as in two other species of Lacertini (Lacerta schreiberi and Timon lepidus) whose sex chromosomes were also studied through comparative genomic hybridization. (bvsalud.org)
The euchromatin conservatism was shown by comparative chromosome painting with stone marten probes in newly built maps of the sable and pine marten. (bvsalud.org)
Variation1
X chromosomes in Cervidae evolved through complex chromosomal rearrangements of conserved segments within the chromosome, changes in centromere position, heterochromatic variation, and X-autosomal translocations. (bvsalud.org)
Species6
This paper describes the preparation of flow-sorted chromosome paints from the Iberian Rock lizard Iberolacerta monticola, exemplifying their subsequent use in cross-species comparisons of chromosome painting. (bvsalud.org)
Furthermore, very conspicuous differences from the standard Lacertini karyotype were observed in the three Pyrenean species of this genus, which included several biarmed metacentrics and a Z1Z2W multiple sex-chromosome system. (bvsalud.org)
With the possible exception of L. schreiberi, all the species of the family Lacertidae described to date appear to share homologous Z chromosomes, which date back to the last common ancestor of the whole group. (bvsalud.org)
Furthermore, we show that the multiple sex-chromosome system of the Pyrenean species of Iberolacerta originated from the fusion of the ancestral W chromosome with one of the shortest autosomes, and provide additional evidence of the fast evolution of DNA sequences linked to the W chromosome in Lacertini.

The family Cervidae is the second most diverse in the infraorder Pecora and is characterized by variability in the diploid chromosome numbers among species. (bvsalud.org)
To track chromosomal rearrangements during Cervidae evolution, we summarized new data, and compared them with available X chromosomal maps and chromosome level assemblies of other species. (bvsalud.org)
Structure1
The introduction of FISH (fluorescence in situ hybridization) marked the beginning of a new era for the study of chromosome structure and function. (biosyn.com)
