A condition described as autosomal recessive maintains that the causative gene is located on an autosome and that both copies of the gene must harbor a causative allele. In most cases of recessive conditions, it is correctly assumed that each parent of an offspring with the trait carries a single causative allele. Carriers for recessive conditions do not typically show phenotypic features. Recessive conditions occur more commonly in offspring of consanguineous unions or in populations with high frequency of carriers for a particular condition.
