答遗传性疾病可根据遗传模式,分为单基因遗传病和多基因遗传病。前者包括显性遗传病和隐性遗传病(孟德尔遗传模式)。后者的特点是多个作用较弱的基因同时与环境因素起作用导致疾病的发生,单个基因、离开了环境因素不能导致疾病的发生。根据不同的糖尿病分型,其遗传特点有不同的解释。1型和2型糖尿病均是多基因 A genetic disease can be divided according to the genetic model, single gene and polygenic disease. The former includes dominant genetic disease and recessive genetic disease (Mendel’s genetic model). The latter is characterized by a number of weak genes that work simultaneously with environmental factors leading to the occurrence of the disease. With a single gene, leaving the environment can not lead to the occurrence of the disease. According to different types of diabetes, the genetic characteristics of different interpretations. Both type 1 and type 2 diabetes are polygenic
