Genetic disorders have been around for a very long time. They are usually caused by recessive genes and can range from minor traits to death. .

Achondroplasia is a type of dwarfism characterized by abnormal proportions of the arms, legs and body, results from impaired cartilage growth. It is a skeletal and muscular disorder transmitted by a single gene. Achondroplasia is a birth defect that is familial, passed on from one generation to the next. This genetic defect of the cartilage cells affects only some of the cartilage in the body, like the spine and limbs. Often those people who suffer from the condition typically have a normal size trunk with a painful, curved spine, a relatively large head, and short arms and legs. Achondroplasia, passed on from one generation to the next, is a defect often transmitted by a single gene. Some one growing up as a dwarf will obviously have social problems. They do not fit in with the rest of society and also have tons of problems doing other things. Things that is as easy as reaching something that's high on shelf or even driving a car.

Albinism, absence of pigment in skin, hair, and eyes, is a genetic birth defect passed on from one generation to the next. Albinism is generally considered to be the first genetic disorder ever recognized. References to it have been found as far back as the Old Testament. Members of any race can be albinos, and other creatures can also inherit this inability to make color pigments. In humans a recessive gene causes albinism. If two carriers of the albinism gene produced children, chances are one in four that they will have a child who is albino. Often the eyes appear to be pink, because the color of blood can be seen through the iris. Albino hair is light yellow to white, and the skin is as white as milk. Because of their lack of pigmentation their skin is easily sunburned and their eyes need to be protected from strong sunlight.
