It is clear from the comparison of the number of AmphiL34 and AmphiS29 genes with that of rat L34 and S29 genes that duplication of L34 and S29 genes occurred in vertebrates like rat. It therefore appears that the housekeeping ribosomal proteins genes such as L34 and S29 also underwent large-scale duplication during the early chordate evolution.

这一结果分别与大鼠7-9个L34拷贝数和14-17个S29拷贝数相比较，证明持家核糖体蛋白基因L34和S29基因在脊椎动物起源与进化过程中发生了大规模扩增，符合两轮基因倍增规律。
