Supernumerary B chromosomes (Bs) are extra karyotype units in addition to A
chromosomes, and are found in some fungi and thousands of animals and plant species. Bs …

B chromosomes represent additional chromosomes found in many eukaryotic organisms.
Their origin is not completely understood but recent genomic studies suggest that they …

B chromosomes are enigmatic elements in thousands of plant and animal genomes that
persist in populations despite being nonessential. They circumvent the laws of Mendelian …

Not necessarily all cells of an organism contain the same genome. Some eukaryotes exhibit
dramatic differences between cells of different organs, resulting from programmed …

The study of B chromosomes (Bs) started more than a century ago, while their presence in
mammals dates since 1965. As the past two decades have seen huge progress in …

Female meiotic drive is the phenomenon where a selfish genetic element alters
chromosome segregation during female meiosis to segregate to the egg and transmit to the …

B chromosomes are enigmatic heritable elements found in the genomes of numerous plant
and animal species. Contrary to their broad distribution, most B chromosomes are non …

The raccoon dog, Nyctereutes procyonoides (NCBI Taxonomy ID: 34880, Figure 1a)
belongs to the family Canidae, with foxes (genus Vulpes) being their closest relatives …

The origin of supernumerary (B) chromosomes is clearly conditioned by their ancestry from
the standard (A) chromosomes. Sequence similarity between A and B chromosomes is thus …

B chromosomes (Bs) revealed more than a hundred years ago remain to be some of the
most mysterious elements of the eukaryotic genome. Their origin and evolution, DNA …
