Albinism

Albinism is a genetic disorder, caused by a dysfunctional gene on an autosomal chromosome that normally produces melanin, a pigment that is responsible for the coloration of our eyes skin and hair. the disease is uncommon, because the gene responsible for albinism is recessive, meaning both parents must give the gene to their child for the gene to be used. this does not mean, however, that both parents must be albinos themselves. in fact, two normal people can have an albino offspring, because they could be carriers of the gene, and since it isnt dominant, it wont appear but they have the capability to pass it on. the disorder occurs in males and females, and of all ethnicities. some cases of albinism are more severe than others. The different types of albinism depend on when the mutation occurs, the more severe cases are caused by a mutation within the gametes where as people with lesser symptoms were probably affected by a random mutation after the 2 gametes met and fertilized. Some symptoms usually include vision problems, sensitivity to sunburn and to bright light glare, very pale skin and hair, and funnily colored eyes such as red or purple (but not always). Albinism is not lethal, but very problematic due to social issues and often legal blindness. besides being prone to skin cancer, albinos have normal life expectancy. also, other organisms besides humans can be organic.
