1. Autosomal dominant genes are modified copies of the gene in a given cell. This is enough for someone to become affected by an autosomal dominant disorder. The person that inherits the given disorder would do so from a parent that is also affected by the same gene. Some disorders that fit into this classification are Huntingtons disease and Marfan syndrome. When a person is affected by an autosomal recessive disorder, both copies will be mutated in these genes. When a person has been diagnoses with an autosomal recessive disorder, the parents will each be a carrier of one copy of each mutated gene, however, they will typically not display any signs of symptoms of having this condition. Autosomal recessive disorders are not necessarily passed down to each and every generation, but can also skip generations as it transforms. Some well-known diseases that are autosomal recessive are cystic fibrosis, as well as sickle cell anemia. X-linked dominant disorders are produced by changes of the X chromosome on the gene. Females have two X chromosomes. A mutation in one of the two copies of the gene of each cell is enough to cause a disorder. Males only have one X chromosome, so metamorphosis in only one copy of the gene from each cell is a foundation for the disorder as well. Males can also not pass the gene on to another male, such as their son. It is also not uncommon for males to experience more severe symptoms or reactions of the disorder than that of a female.
