WebPlant breeders can use self-pollination as a type of inbreeding, creating plants that are genetically more identical and that produce identical offspring after many generations. Crossbreeding This is often used to produce offspring with desirable characteristics from two different individuals. WebA big factor here is that many plants can have more copies of their DNA than vertebrates can. Vertebrates are typically diploid (two DNA copies), but plants are often polyploid (more than two copies of DNA). If a population of humans were to inbreed for a few generations, the children could end up with double copies of a lot of recessive genes.
