Autosomal dominant genes
In the case of autosomal dominant genes, a single abnormal gene on one of the autosomal chromosomes (one of the first 22 non-sex chromosomes) from either parent can cause the disease. One of the parents will have the disease (since it is dominant) in this mode of inheritance and that person is called the CARRIER. Only one parent must be a carrier in order for the child to inherit the disease.
