How gene drive works
Gene drive is a genetic technology that can permanently change the traits of a species. It works by altering the likelihood of offspring inheriting a specific gene from their parents.
Normally genes have a 50% chance of being inherited: gene drive technology could increase this to nearly 99%. This means that over several generations, a selected trait could become increasingly common in a specific species.
Gene drive only works in species that reproduce sexually, and it works best in species which have a short lifespan and produce many offspring.
