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 ...

MZ twins are derived from the same one-cell zygote, thus, share not only their genomic sequence but also the same initial epigenetic factors except for egg cleavage asymmetry. ...
