遗传病的遗传信息是通过致病基因来传递的。致病基因的传递方式在单基因遗传病和多基因遗传病是不同的。一、单基因遗传这类疾病一般与一对基因有关,依传递方式特点,又可分以下几类。 (一)常染色体显性遗传(显性遗传) 一种疾病有关的基因位于常染色体上,这种基因的性质是显性的,这种遗传方式就叫常染色体显性遗传,这种疾病可以叫常染色体显性遗传病。
The genetic information of genetic disease is transmitted through pathogenic genes. Pathogenic gene transfer in the single-gene disease and polygenic disease is different. First, single-gene inheritance of such diseases are generally associated with a pair of genes, according to the characteristics of the mode of delivery, but also can be divided into the following categories. (A) autosomal dominant (dominant) a disease-related genes in the autosomal, the nature of this gene is dominant, this genetic means is called autosomal dominant inheritance, the disease can be Called autosomal dominant genetic disease.
