Reassortment

A variety of recombination called reassorfwent occurs with viruses that have segmented genomes, whether these are ssRNA or dsRNA and consist of 2 (Amiaviridae), 3 {Bunyaviridae), 8 (influenza A virus), 10 (Reovirns), 11 (Rotavirus), or 12 (Coltwirus) segments (Fig. 4-1B). In a single cell infected with two related viruses within any of these groups, there is an exchange of segments with the production of various stable reassortants. Reassortment occurs in nature and is an important source of genetic variability.
