But about 15 percent of identical twin pairs have more than that.

但是大约有15%的同卵双胞胎的差异更大。

As Dr. Spector questioned these food myths, he remembered an earlier study involving identical twins, pairs of brothers or sisters with the same genes.

当斯佩克特博士质疑这些食物迷信时，他想起了一项涉及同卵双胞胎的早期研究，同卵双胞胎是拥有相同基因的一对兄弟或姐妹。

In 2015, a meta analysis, a study of studies, found this pattern across thousands of studies following over 14 million twin pairs across 39 countries.

2015 年， 一项荟萃分析， 一项对研究的研究，在对 39 个国家超过 1400 万对双胞胎的数千项研究中发现了这种模式。

In one mega-study of eleven thousand twin pairs in four countries, that correlation kept increasing from middle-childhood to adolescence to young adulthood and continued to increase through adulthood.

在四个国家对一万一千对双胞胎进行的一项大型研究中，这种相关性从童年中期到青春期再到青年期一直在增加， 并在成年后继续增加。
