The study of chromosome evolution is undergoing a resurgence of interest owing to
advances in DNA sequencing technology that facilitate the production of chromosome-scale …

With more than 70,000 living species, vertebrates have a huge impact on the field of biology
and research, including karyotype evolution. One prominent aspect of many vertebrate …

Microchromosomes, once considered unimportant shreds of the chicken genome, are gene-
rich elements with a high GC content and few transposable elements. Their origin has been …

The karyotype of most birds has remained considerably stable during more than 100 million
years' evolution, except for some groups, such as parrots. The evolutionary processes and …

Songbirds have a species number close to that of mammals and are classic models for
studying speciation and sexual selection. Sex chromosomes are hotspots of both processes …

Abstract The Qinghai-Tibet Plateau (QTP), possesses a climate as cold as that of the Arctic,
and also presents uniquely low oxygen concentrations and intense ultraviolet (UV) radiation …

Background Ducks have a typical avian karyotype that consists of macro-and
microchromosomes, but a pair of much less differentiated ZW sex chromosomes compared …

The chicken continues to hold its position as a leading model organism within many areas of
research, as well as being a major source of protein for human consumption. The First …

The structure and organization of a species genome at a karyotypic level, and in interphase
nuclei, have broad functional significance. Although regular sized chromosomes are studied …

Emu and other ratites are more informative than any other birds in reconstructing the
evolution of the ancestral avian or vertebrate karyotype because of their much slower rate of …
