whose一定指代人吗？是否有指代物的嫌疑？
例og 141
141. 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.
og解释中没提whose是否有指代歧义。但我想whose表谁的，那也有可能是人的，也有可能是物的，所以如果whose前面有两个名词可以指代的话，就出现了歧异。就象这题，whose可以指twins,也可以指transplants.所以whose的用法是错误的。
