And scientists in the field remain puzzled by the fact that most identical twins (who share 100% of their genes) do not die from the same diseases. As a result, many in the scientific community are beginning to predict a decline in the role of the gene in pinpointing the root causes of diseases.
但是，尽管有证据表明大部分疾病都有清晰的基因因素，但解释这些疾病的基因只有一小部分被找到了。该领域的科学家仍被一个事实所困扰：同卵双胞胎（基因100%相同）并不因同样的疾病而死亡。于是科学界许多人开始预言，基因在准确定义病根方面的作用将降低。
