Dominant Genetic Condition

An inherited condition in which one parent carries an abnormal dominant gene. More technically, a single gene of the gene pair that produces a physical characteristic (such as hearing loss) without reference to the other gene in the gene pair. Dominant characteristics are passed by only one parent. Thus each child born to a parent with a dominant gene for hearing loss will have a 50% chance of being hard of hearing himself and will carry this dominant gene, and a 50% chance of having normal hearing and not carrying the dominant gene.
