Avoiding self-fertilization also allows plants to more easily keep beneficial mutations and provides a degree of protection against some harmful mutations , igi said .
igi说,避免自花受精的植物也可以更加容易地保持有利的突变,并可以一定程度阻止一些有害突变。
The findings are reported in the oct. 22 issue of science by igi and lead author emma goldberg , postdoctoral research associate in biological sciences .
Goldberg and igi measured the long-term effects of self-fertilization , which is caused by frequent mutations and is difficult to lose once a plant acquires it .

" We found those species that avoid self-fertilization diversify faster , giving them a long-term advantage , " goldberg said . " It 's a trade-off , " igi added .
goldberg说,“我们那些不自交的植物多样化速度快,这使得它们拥有了一个长期优势”。
