Next time you bite into a slice of watermelon or a cob of corn, consider this: these familiar fruits and veggies didn’t always look and taste this way.
Foods such as bananas and eggplants have been selectively bred over centuries (which is a different process than splicing genes, referred to as genetically engineering) so they have traits which humans prefer, such as fewer seeds and tastier flesh.
Selective breeding entails a farmer selecting and growing crops that have preferred traits so that over time, the majority of the crop produces foods which are tastier and easier to eat. Wild watermelon, for example, has been bred so that it produces more flesh than seeds. Bananas, as well, once had hard more hard seeds than the sweet edible portion.
While GMOs may involve splicing genes from other organisms (such as bacteria) to give plants desired traits – like resistance to pests, selective breeding is a slower process whereby farmers select and grow crops with those traits over time.
- A genetically modified organism, or GMO, is an organism that has had its DNA altered or modified in some way through genetic engineering. In most cases, GMOs have been altered with DNA from another organism, be it a bacterium, plant, virus or animal; these organisms are sometimes referred to as “transgenic” organisms.
