The recent advances in DNA sequencing technology are enabling a rapid increase in the
number of genomes being sequenced. However, many fundamental questions in genome …

B chromosomes are supernumerary chromosomes which are often preferentially inherited,
deviating from usual Mendelian segregation. The balance between the so-called …

Most recent initiatives to sequence and assemble new species' genomes de novo fail to
achieve the ultimate endpoint to produce contigs, each representing one whole …

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 …

Monitor lizards are unique among ectothermic reptiles in that they have high aerobic
capacity and distinctive cardiovascular physiology resembling that of endothermic …

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

For many years, parasitic B chromosomes have been considered genetically inert elements.
Here we show the presence of ten protein-coding genes in the B chromosome of the …

Accessory, supernumerary, or—most simply—B chromosomes, are found in many
eukaryotic karyotypes. These small chromosomes do not follow the usual pattern of …

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 …
