Autosomal recessive refers to a form of inheritance that is present in some genetic diseases. “Autosomal” means that the gene involved is found on one of the numbered, or non-sex chromosomes. “Recessive” means that two copies of the mutation that causes the disease are needed for the disease to be present. In other words, the child who has the genetic disease receives copies of the disease allele from both parents.
