Some feel that transgenesis (the transfer of cloned genetic material from one species or breed to another) is "really scary, and could result in grotesque mutations," but in fact the chloroplasts and mitochondria in plants are transgenic material, having evolved from bacteria. They may have been exogenous back in the mists of our primordial past, but they've become indispensable since then.
有人認為跨物種轉殖基因「很可怕，會長出『異形』變種」，但事實上，植物中的葉綠體、粒腺體，本來就是跨物種從細菌來的，如今卻已成為體內最重要的一份子。
