Alisha and Rob would like to have children. A genetic counselor tells them that they are both carriers of a certain genetic disease. What does this mean?

• There is a very high probability that one or both of them will develop the disease at some point in the future.

• They both have an allele for the disease and could pass this allele on to their children, even though neither of them has the disease.

• They both have the disease, but there is a very low probability that they will pass it on to their children.
