What is Genetics?
Genetic Diseases A genetic disease involves an abnormality in genetic material. Otherwise, there could be mutations or changes in an organism’s DNA. A genetic disease can be inherited through a family. There are three types of disorders: Chromosomal Disorders, Single Gene Disorders, and Multifactorial Disorders. Chromosomal Disorders are caused by too many chromosomes, not enough chromosomes, or the chromosome structures are abnormal. Polymelia is considered as a Chromosomal Disorder. Some other diseases that are considered as a Chromosomal Disorder are Down Syndrome and Turner Syndrome. Single Gene Disorders are caused by defects in individual genes. Gene defects cannot be detected by chromosome analysis. Thalassemia …show more content…
The limbs are often deformed and smaller than normal limbs. This could have happened due to conjoined twins, known as Siamese twins (For humans only). For this to occur, one of the conjoined twins would need to die and decay during the mother’s pregnancy. If there were limbs attached to the dead baby, the limbs would be adsorbed by the living baby. Polymelia is not only found in humans, it is found in animals, too. For this to happen in animals, the animal’s chromosomes would have to have multiple breaks in it. Otherwise, getting this disease could be a mutation from medicine or some other environmental causes.
How is Polymelia Diagnosed? What are the Symptoms? Polymelia happens when a woman is pregnant. The only way Polymelia is diagnosed is through vision and no symptoms are present in this disease. There would be a presence of limbs attached to an organism. There are certain types of Polymelia cases. Cephalomelia is one case. This is where an extra limb is attached to the head of an organism. There can be a limb attached to the backbone of an organism which is called Notomelia. Thoracomelia is an extra limb attached to the thorax of an organism. Finally, Pyromelia is an extra limb attached to the pelvis of an organism.
