題組內容
一、請解釋下列兩對基因間交感作用之意義與寫出其 F
2
分離比。
(四)重複基因(duplicate gene)
其他申論題
五、下表數據為一世代研究探討暴露 X 與疾病 Y 相關性之研究結果。研究 結束後研究者被告知他所使用診斷疾病 Y 的工具其敏感度(sensitivity) 與精確度僅約0.8(無論暴露狀況),意即該研究者現在所得到數據(如 下表所示)極可能是受到測量誤差所致。請計算校正敏感度與特異度後 之相對危險性,意即,沒有診斷誤差情況下之相對危險性。此外,若用此診斷工具在一個疾病 Y 盛行率為20%的族群中進行疾病診斷,請計算一名暴露 X 者會被診斷出疾病 Y 的機率為何?(20分)

一、英譯中: Backaches, which lame an estimated 5.4 million Americans each year, have resisted all medical miracles. A leading treatment for recurring low back pain is still the sofa, upon which a patient is supposed to recline, usually for at least a week and often much longer, until the pain goes away. Lingering backaches keep more workers off the job than any other ailment, costing the nation $16 billion in medical bills and lost wages annually. But it now appears that you shouldn’t take a bad back lying down. Medical researchers in Sweden have shown that the best remedy for the most common type of backache is exercise,and that the afflicted should be active even if it hurts.
