What Is Vertical Transmission?

Vertical transmission is a genetic disease that has a certain incidence among individuals with a blood relationship, and generally does not extend to individuals with no blood relationship, such as a spouse, aunt, and aunt This is one of the main characteristics that distinguish genetic diseases from other diseases. Many genetic diseases, especially those with a dominant inheritance, tend to be familial, but not all genetic diseases are familial. For example: some patients are the first cases of mutations, the first in the family; some autosomal recessive genetic diseases are often sporadic; some patients with chromosomal diseases can not be observed vertically because they are not able to live or reproduce Sporadic cases were passed on. Therefore, it cannot be considered that the disease spread is not a genetic disease. At present, a couple in our country only has one child, and what we see is often distributed. ^[1]
