WebFeb 22, 2024 · Although fission and fusion of chromosomes are unlikely to be the only processes that have led to speciation between these butterflies, this study shows that these rearrangements can directly promote reproductive isolation and may be involved in speciation when karyotypes evolve quickly. WebFeb 28, 2007 · Centric fission of chromosome 11 has resulted in two stable telocentrics. There was no tendency to fuse again or to associate with acrocentrics as verified in 50 additional metaphases. Three distinct fluorescent spots were detected with the PRINS reaction in more than 100 interphase nuclei. Open in a separate window Fig. 2 immortal clothes

WebBinary fission is an asexual form of reproduction, meaning that it does not involve production of eggs and sperm or mixing of genetic material from two individuals. Except in the case of rare mutations, or changes in DNA sequence, binary fission produces daughter cells that are genetically identical to the mother cell.
