fraternal twins

基本解释

The scientists made this conclusion based on the fact that identical twins performed much more similarly than fraternal twins.
同卵双生双胞胎比以卵双生双胞胎的心智状况更为接近，科学家据此得出上述结论。
In other words, their senses of what was fair were similar. No such correlations were seen in the behaviour of fraternal twins.
换句话说，他们的公平感是很相似的，而在异卵双生的双胞胎中就没有发现这样的关系。
Studies of the occurrence of depression in twins show a 70 percent chance for both identical twins to suffer from depression, which is twice the rate of occurrence in fraternal twins.
关于双胞胎的发病几率，研究表明同卵双胞胎的发病几率为70%，是异卵双胞胎发病的两倍。
