Inbreeding and genetic drift
WebJan 23, 2024 · By. Anne Marie Helmenstine, Ph.D. Updated on January 23, 2024. Inbreeding is the process of mating genetically similar organisms. In humans, it's associated with consanguinity and incest, in which close relatives have sexual relationships and children. Inbreeding violates modern social norms but is fairly common in animals and plants. WebGenetic drift refers to spontaneous changes in genomic DNA that can arise in any generation of mouse breeding. Drift comes in the form of DNA replication or repair mistakes that get passed on in the germ cells. Drift …
