Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

A genome-wide survey of segmental duplications that mediate common human genetic variation of chromosomal architecture. [PDF]

, 2004
Recent studies have identified a small number of genomic rearrangements that occur frequently in the general population. Bioinformatics tools are now available for systematic genome-wide surveys of higher-order structures predisposing to such common ...

Multiple chromosomal rearrangements in a hybrid zone between Littorina saxatilis ecotypes

Molecular Ecology, 2019
Both classical and recent studies suggest that chromosomal inversion polymorphisms are important in adaptation and speciation. However, biases in discovery and reporting of inversions make it difficult to assess their prevalence and biological importance.

Karyotypic Evolution of the Common and Silverleaf Sunflower Genomes

The Plant Genome, 2009
Silverleaf sunflower ( Torrey and Gray) has been an important source of favorable alleles for broadening genetic diversity and enhancing agriculturally important traits in common sunflower ( L.), and, as the closest living relative of , provides an ...

Genome architecture is a selectable trait that can be maintained by antagonistic pleiotropy [PDF]

, 2013
Chromosomal rearrangements are mutations contributing to both within and between species variation; however their contribution to fitness is yet to be measured.

Case report: Optical genome mapping revealed double rearrangements in a male undergoing preimplantation genetic testing

Frontiers in Genetics, 2023
Chromosome rearrangement is one of the main causes of abortion. In individuals with double chromosomal rearrangements, the abortion rate and the risk of producing abnormal chromosomal embryos are increased.

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]

, 1994
Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

Replication timing and epigenome remodelling are associated with the nature of chromosomal rearrangements in cancer

Nature Communications, 2019
DNA replication timing is known to facilitate the establishment of the epigenome, however, the intimate connection between replication timing and changes to the genome and epigenome in cancer remain largely uncharacterised. Here, we perform Repli-Seq and
