Multiregional origin of B chromosomes in the grasshopper

Although the intraspecific hypothesis likely applies to many, perhaps most, B chromosomes, there is sound evidence that some of them have arisen through interspecific hybridization (see McAllister and Werren 1 ...

DNA supercoil
DNA supercoiling refers to the over- or under-winding of a DNA strand, and is an expression of the strain on that strand. Supercoiling is important in a number of biological processes, such as compacting DNA. Additionally, certain enzymes such as topoisomerases are able to change DNA topology to facilitate functions such as DNA replication or transcription. Mathematical expressions are used to describe supercoiling by comparing different coiled states to relaxed B-form DNA.As a general rule, the DNA of most organisms is negatively supercoiled.
