WHAT IS ALBINISM?

The quality of having no pigment Cannot absorb any light All colors are reflected off, making organisms

look white Albinos are the organisms that have the

disease albinism

Page 4: Albinism

HOW IS THE DISEASE INHERITED?

Both copies of the parents’ genes “block” the production of melanin (pigments)

If one parent allows melanin, and the other does not, the offspring will look normal, but will have the recessive gene of albinism.

Being albino is recessive. Being “normal” is a dominant trait.

SYMPTOMS

No melanin inside you whatsoever White/light pink hair, skin, scales, or feathers Red/light blue eyes

The redness is from your blood vessels. It does not mean that there is red melanin.

Eyes will also not be able to focus well due to the light

Wear contacts or sunglasses to help eyes focus around others

Frequent skin tests No melanin Easier for cancer
