Explanation:

Genetic disease is one that is caused by changes in genetic material, that is, in DNA. Many of these genetic diseases are hereditary, that is, they are passed from parents to children. An example of this can be seen in the above question, where Nina presents a condition that was inherited from her mother. This condition represents an inherited genetic disease.

Not every genetic disease is inherited. Cancer, for example, is a genetic disease because it is caused by mutations in DNA, but it is not passed on to children. This is because cancer-causing mutations occur throughout a person's life in non-gamete cells that are not transmitted to the next generation.
