1 Answer

Answer :

DefinitionAutosomal 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.Alternative NamesGenetics - autosomal recessive; Inheritance - autosomal recessiveInformationInheriting a specific disease, condition, or trait depends on the type of chromosome 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. Recessive inheritance means both genes in a pair must be defective to cause disease. People with only one defective gene in the pair are considered
