1疑问杨国锋人教版高中《生物·必修2·遗传与进化》P.91给出了某种遗传病的发病率计算公式:某种遗传病的发病率=某种遗传病的患病人数/某种遗传病被调查人数×100%。此处患病率计算公式是否妥当?这样计算是不是因为单基因遗传病都无法治愈,发病后终生患病?2讨论杨国锋发病率是指某一人群1年内新发生某种病的频率,可用十万分率、万分率表示,也可用千分率、百分率表示。其公式为:某病发病率(1/10 000)=
1 Questions Yang Guofeng PEP Senior High School “Biology · Compulsory 2 · Genetics and Evolution” P.91 gives the formula for calculating the incidence of a genetic disease: the incidence of a genetic disease = the number of people suffering from a genetic disease / A genetic disease was investigated × 100%. Here is the formula for calculating the prevalence is correct? This calculation is not because of single-gene disease can not be cured, the disease after the onset of life-threatening? 2 Discussion Yang Guofeng incidence refers to the frequency of occurrence of a disease in a population within 1 year, available One hundred thousand, million, said the percentage can also be used, the percentage said. The formula is: a disease incidence (1/10 000) =
