How hireditary illness is being transmitted?

Hereditary illnesses are passed down from parents to children through genes. Genes are segments of DNA that contain instructions for the development and functioning of an organism. When a person has a hereditary illness, they have a mutation in a gene that codes for a protein that is essential for normal function. This mutation can be inherited from either parent, or it can occur spontaneously.

In some cases, a hereditary illness is caused by a single mutation in a single gene. In other cases, it is caused by a combination of mutations in multiple genes. The inheritance pattern of a hereditary illness depends on the specific gene or genes that are involved.

Some hereditary illnesses are dominant, which means that only one copy of the mutated gene is needed to cause the illness. Other illnesses are recessive, which means that two copies of the mutated gene are needed to cause the illness.

The risk of inheriting a hereditary illness depends on the inheritance pattern of the illness and the family history. If you have a family history of a hereditary illness, you should talk to your doctor about your risk of inheriting the illness.
