What is another word for b chromosome?
Pronunciation: [bˈiː kɹˈə͡ʊməsˌə͡ʊm] (IPA) 
The term "B chromosome" refers to an additional chromosome found in some organisms, usually in addition to the normal chromosome complement. However, there are several other terms used in scientific literature to refer to these extra chromosomes. Some researchers refer to them as accessory chromosomes, supernumerary chromosomes, or extra chromosomes. Other terms include heterochromatic supernumerary chromosomes, or simply B or C chromosomes. The classification of these chromosomes varies depending on the species, and some organisms may have unique names for their additional chromosomes. Despite these different names, they all refer to the same phenomenon of additional, nonessential genetic material in an organism's genome.
