X chromosome sex-link disorder… In an autosomal dominant disorder, the mutated gene is a dominant gene located on one of the nonsex chromosomes (autosomes). It manifests itself in the heterozygote (designated Aa), who receives a mutant gene (designated a) from … Autosomal refers to the fact that whatever gene is involved is found on one of the first 22 chromosomes (called the autosomes) and not on the X or Y chromosome (the sex chromosomes). heterozygous . The parents each have one CF and one normal paired gene and so are said to be heterozygous for CF. Autosomal Recessive . Autosomal dominant disorders include all the following EXCEPT .
