Unlike transplants between identical twins, whose genetic endowment is the same, all patients receiving hearts or other organs must take antirejection drugs for the rest of their lives.

(A)Unlike transplants between identical twins, whose genetic endowment is the same

(B)Besides transplants involving identical twinswith the same genetic endowment

(C)Unless the transplant involves identical twinswho have the same genetic endowment

(D)Aside from a transplant between identical twins with the same genetic endowment

(E)Other than transplants between identical twins,whose genetic endowment is the same

In A and B, the phrases beginning Unlike... and Besides... modify patients, the subject of the main clause; thus A absurdly states that Unlike transplants ..., patients... must take ... drugs, and B that all patients except for transplants... must take ... drugs.In B and D the expression identical twins with the same genetic endowment wrongly suggests that only some identical twin pairs are genetically identical. In E, the construction Other than transplants..., all patients ... must take... drugs illogically suggests, as in B, that some patients are transplants. Choice C, the best answer, solves these problems by using a clause introduced by Unless to describe the exception to the rule and a nonrestrictive clause beginning with who to describe the characteristic attributed to all identical twins.

我看不懂上面的解释，哪位帮我再讲讲……

意思是unlike, besides, other than, aside from都需要同patients主语一致吗？是这要意思吗？还有红色标记的部分是什么意思呢？没弄明白……

个人理解：
OG的思想：with和whose对于主语的限定范围不同
n. with adj. 表示这种adj特征只是部分该事物的特征
n. whose be adj. 表示该事物.全部都具备adj这种特征。

欢迎大牛指正

同意楼上的解说
解释"In B and D the expression identical twins with the same genetic endowment wrongly suggests that only some identical twin pairs are genetically identical" 中一开始我把some看成了same，所以特别难理解。但是回过来，用some，则明朗多了。
如果用了identical twins with the same genetic, 就是说这个same genetic 是其中一些identical twins 才具有的。(这就有点违背了原文的意思哦)。如果换成用非限制性定语从句(nonrestrictive clause)来修饰的话，就是说这个只要是identical twins那么他们就有same genetic了。那就与原意配上了。
不知道说的对不对？

1、表示比较或者平行的时候，要求进行比较或者平行的对象要对等，要有可比性是同性质的东西（说的好啰嗦呀。。。）

2、GMAT中有一个非常非常常见的错误，就是本题中的这种：把一个完整的概念用名词或者“介词+。。。”替代，然后造成对概念的解释不完整。

identical twins who have the same genetic endowment 和
identical twins with the same genetic endowment 楼主体会下

还有好多好多例子的在OG prep或者其他资料上

我认为是要保持同后面主句的主语一致，xdf的老师也有讲过此类题目，都是看主语是否一致。否则句子的逻辑意思就错误了。不好意思，红色标记我没看到，所以没回答。呵呵
