noun
- genetics any of several processes by which genetic material of different origins becomes combined. It most commonly occurs between two sets of parental chromosomes during production of germ cells

Natural selection leaves subtle signatures on our genome, but these marks can erode over generations due to recombination, where segments of DNA are shuffled and diluted.
When this occurs, there is potential for a “recombination” of the genetic code from both viral strains.
This reshuffling, due to random segregation of chromosomes and meiotic recombination, is important in generating novel and beneficial genetic configurations in natural populations and during breeding.
One discovery is particularly interesting with regard to the emergence of new viruses: In host animals that are simultaneously infected with different viruses, a recombination of viral genes can occur during virus replication.
Chun's new research builds on his lab's landmark publication in Nature in 2018 that described how somatic gene recombination in neurons can produce thousands of new gene variants within Alzheimer's disease brains.
