Chromosomes are major components of cells, packing the genetic material in a perfect organized structural and functional pattern. However, the chromosomes behavior during cell cycle is subjected to genomic rearrangements producing a wide variety of functional consequences with impact in cell disorders and also generating evolutionary novelties. Although several factors that mediate genomi…

Despite the nature of the name "B chromosomes" descend from the idea of extra and dispensable elements of the genome, different from the so called "A chromosomes" and from aneuploidy cases (Beukeboom, 1994), its presence throughout most broad eukaryote clades and its heterogeneity in evolution and behavior amongst species prevent a unified conceptual definition (Camacho, 2005). As a matte…
Genomic changes represent a primary mutational mechanism that generates novel genetic raw material to evolution. B and sex chromosomes are part of a complex genomic system originated repeated times across eukaryotic evolutionary history. B and sex chromosomes harbor notorious shared traits in relation to the other chromosomes of the genome, associated to their origin, composition, and evo…
Holochilus sciureus (HSC) (2n = 56+1B, and FN = 56) belongs to the rodent tribe Oryzomyini, the most taxonomically diverse tribe of the Sigmodontinae subfamily. Cytogenetic studies on the Oryzomyini reflect such diversity revealing an exceptional range of karyotype variability. Comparative cytogenetics by Zoo-FISH on 15 Oryzomyini species using the entire chromosome set of HSC revealed a …
Sex chromosomes evolved several times in the most diverse groups of the tree of life. Duringthis process occurs basically the acquisition of a sex-linked allele in the proto-Y or proto-W chromosome in the heterogametic sex. After that, the sex chromosome could differentiate by accumulation of repetitive DNAs sequences and other alleles that favor one of the sexes. A common pattern for the…

B chromosomes, (Bs) also known as supernumerary or accessory chromosomes, are additional and non-essential constituents of karyotypes. The genetic origin, evolution and composition of Bs has remained an intriguing debate. We have sequenced the complete genomes of three species including the fishes Astyanax mexicanus, Astyanax correntinus and the grasshopper Abracris flavolineata with and …
B chromosomes are extra elements identified in the genome of several groups of eukaryotes and are traditionally referred as not functional units. The cichlid fish Astatotilapia latifasciata has B chromosomes ranging from zero to two among individuals and its origin, evolution and functional aspects are relatively well understood, but its epigenetic effects are still poorly explored. Trans…
The eukaryote genome is composed of classical DNA sequences and selfish elements, which do not obey the laws of Mendelian inheritance. Among these sequences are transposons, cytoplasmic factors and B chromosomes. Along the advances in chromosomal studies, B chromosomes are no longer seen as parasitic elements, and recent data have shown these chromosomes may have important biological role…
