一、遗传流行病学概念遗传流行病学(Genetic Epidehiology)是流行病学一个新的分支,主要是研究人类疾病中那些是有遗传性的,那些是没有遗传性的。又因为流行病学是研究疾病病因和发病因素的学科,所以遗传流行病学的任务也包括研究影响遗传疾病的各种环境因素和先天因素(即遗传因素)的作用,以及遗传疾病在人群中的分布和预防对策。二、遗传与变异遗传和变异是生物界的普遍规律。正是因为有了遗传性,生物才能保持形态和生理的特征的恒定,否则物种经常变来变去,难以辨去,人类自己也不知变成何样。也正是因为有变异,才可以使各种生物得以进化和发展。人类疾病也受遗传和变异的影响,例如猩红热,其病原是溶血性链球菌,主
I. GENETIC EPIDEMIC CONCEPTS Genetic Epidemiology is a new branch of epidemiology that focuses on the genetic aspects of human disease and those that are not hereditary. And because epidemiology is the discipline that studies the etiology and pathogenesis of disease, the task of genetic epidemiology involves studying the effects of various environmental and innate (genetic) factors that affect genetic disease and the role of genetic disease in the population Distribution and prevention measures. Second, genetic and mutation Genetic and mutation is the universal law of the biological world. It is because of the hereditary nature that a living organism can maintain its morphological and physiological traits constant, otherwise the species often change and become illegible, and human beings themselves do not know what they are. It is also because of the variation that various organisms can be evolved and developed. Human diseases are also affected by inheritance and variation, such as scarlet fever, the pathogen is hemolytic streptococcus, the main
