WebKaryotype, chromosome number and composition, is a basic characteristic of species and its changes are frequently associated with speciation. Karyotype conversion, from mostly telocentric (centromere terminal) to mostly metacentric (centromere internal), typically reflects fixation of Robertsonian (Rb) fusions, a common chromosomal rearrangement …
