If this disease is genetic--what are the possible genotypes of the parents? If the disease is a chromosomal abnormality, describe the abnormality.

Thousands of infants are born deaf each year, over half having a hereditary disorder. Neither parent may not have the gene for deafness at all and the child could still be born with a mutated gene for hearing. If one parent did have the faulty gene, you could look back at their family history of hereditary deafness and be able to determine their genotype, as well as with the other parent. This abnormality in a person of any age is associated with the malformation of the certain gene that deals with hearing and will affect them for a lifetime.
