• jamuuj: One feature found among an autosomal recessive pedigree is that heterozygotes have a normal phenotype. Autosomal recessive are several ways that a trait, disorder or a disease can be passed down through families. Autosomal disorder means that two copies of an abnormal gene must be present  for the disease or trait to develop, and therefore, a heterozygote will show a normal phenotype.
