structural_biologist writes: Genes normally have a 50-50 chance of being passed from parent to offspring, but scientists may have figured out a way to create genes that show up in offspring with a much higher frequency. "One type of gene drive influences inheritance by copying itself onto chromosomes that previously lacked it. When an organism inherits such a gene drive from only one parent, it makes a cut in the chromosome from the other parent, forcing the cell to copy the inheritance-biasing gene drive—and any adjacent genes—when it repairs the damage." When introduced into the wild, organisms containing gene drives would breed with the population, quickly spreading the modified genes throughout the ecosystem. While the technology could help prevent the spread of malaria and manage invasive species, many scientists worry about the wide-ranging effects of such a technology and are calling for its regulation.
