How Are Diseases Hereditary?

Dominant genetic diseases are caused by a mutation in one copy of a gene. If a parent has a dominant genetic disease, then each of that person's children has a 50% chance of inheriting the disease. Dominant diseases can also occur spontaneously; this happens when a random mutation in one gene occurs at conception.

How hereditary diseases are passed?

Hereditary Diseases are passed on from one generation to another through defective genes. These diseases are transmitted in the same family. The chromosomes in the humans are responsible for passing the traits from the parent to the offspring.

Are all genetic diseases inherited?

Genetic disorders are typically inherited (passed down) in either a dominant or recessive manner. We each have two copies of every gene on our 22 numbered chromosomes.
