autosomal inheritance, a pattern of inheritance in which the transmission of traits depends on the presence or absence of certain alleles on the autosomes. The pattern may be dominant or recessive, and males and females are usually affected with equal frequency. The majority of hereditary disorders are the result of a defective gene on an autosome. Kinds of autosomal inheritance are autosomal-dominant inheritance and autosomal-recessive inheritance. See also inheritance.
Information. Inheriting a specific disease, condition, or trait depends on the type of chromosome that is affected (autosomal or sex chromosome). It 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.t also depends on whether the trait is dominant or recessive.
