和其他生物一样,四叶草的幸运需要DNA来控制表达。但令人惊奇的是,苜蓿的基因非常复杂,是什么导致其基因突变长出四片叶子,这仍是未解的生物之谜。世界上有300多种苜蓿,与代表幸运的四叶草联系在一起的类型是常见的白苜蓿(因其会开出蓬松而美丽的白色花朵,故有此名)。这就像猫多长了一个爪子,我们知道其中有基因原理,以及常常发生的基因突变。科学 Like other creatures, Clover’s luck requires DNA to control its expression. But surprisingly, the gene of alfalfa is very complex, what led to the mutation of the gene out of four leaves, which remains mystery of unsolved creatures. There are over 300 species of alfalfa in the world, and the type associated with the lucky clover is common alfalfa (because of its fluffy, beautiful white flowers). It’s like cats have a paw longer, we know that there are genetic principles, and the gene mutation that often happens. science
