Genetic diseases

A genetic disease is caused by an alteration of the genome (all the genetic information possessed by an organism). A genetic disease can be hereditary or not. If the altered gene is present in sexual cells (ovules and sperm) is hereditary, if it affects the rest of cells, no.

Some genetic diseases are: daltonism (you are not able to distinguish colors); hemophilia (affects men and can not stop bleeding) or Sickle cell anemia.
