WebViruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when coinfecting viruses exchange genetic information, creating a novel virus. 2 WebGenetic recombination is the exchange of part of genome between two genetic entities. There are two kinds of recombination: self-recombination and recombination with host. Self recombination occurs when two closely related viral genomes recombine by homologous crossing over. This happens for DNA viruses and is very common in prokaryotic viruses.
