Definition. Autosomal recessive is one of several ways that a trait, disorder, or disease can be passed down through families. An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop.t also depends on whether the trait is dominant or recessive. A mutation in a gene on one of the first 22 nonsex chromosomes can lead to an autosomal disorder. Genes come in pairs. One gene in each pair comes from the mother, and the other gene comes from the father.
