**http://en.wikipedia.org/wiki/File:Albino_girl_honduras.jpg** Albinos have little to no pigment in there skin, hair or eyes.
It affects people from all races.
1 in 17,000 have albinism in the U.S.A.
Types:
Oculocutaneous Albinism (OCA)- involves the eyes, skin, and hair
Ocular Albinism (OA)- involves just the eyes, the skin and hair similar or lighter than other family members.
The genes for OCA are located on autosomal (body) chromosomes.
Albinism is a recessive trait.
Both parents must carry a defective OCA gene to have a child with albinism.
When both parents are heterozygous (carriers) there is a 1 in 4 chance that the baby will be born with albinism.
This type of inheritance is autosomal recessive.
For OA the defected gene is on the X chromosome.
To have OA a male child has to inherit one defected gene from his carrier mother.
Almost all people with OA are males because females have two copies of the X chromosomes while males only have one.

Symptoms
Their skin is extremely light in color.
Hair color is light or white.
Eyes appear light or pink.

Vision Problems- poor vision, sensitive to bright lights, distorted images, crossed eyes, rapid movements of the eyes, and they could be far or near sighted.

Treatment
There is no cure for Albinism.
Protect the skin by wearing sunscreen with an SPF of 15 or higher, and cover as much skin as possible when in the sun.
Wear sunglasses with UV protection.
Surgery is capable of fixing eye problems.
If skin cancer occurs it can be removed.

Albinism in animals
It occurs the same way in animals as it does in humans.
Pairing of recessive genes. (recessive inheritance).
300 species of animals in North America have albino individuals.
Animals can be pure or partiall albino.
Pure albinos usually pink eyes, nails, scales, and skin

CV-8F-ATA- I thought the layout of your page was great! The first picture really fascinated me because I have never seen anyone like that before and it really put things in prospective. I thought your first video was a tad boring and a little long. Overall, I thought it was a very good page!(:
