Genetic reassortment

Genetic reassortment is a process that occurs during the reproduction of certain viruses, particularly those with segmented genomes, like influenza. When two different strains of a virus infect the same cell, their genetic material can mix and exchange segments. This results in new combinations of genes, producing a novel virus with traits from both parent viruses. This genetic shuffling can lead to new virus strains, potentially affecting their ability to spread, cause disease, or evade the immune system. It's a key mechanism for viral evolution and can impact public health, requiring continuous monitoring of viral strains.
