Albinism is a condition where the external pigment fails to develop resulting in the person on having a light skin ,white hair and Pink eyes.
This is due to lack of melanin in the malpghian layer of the skin.
Albinism occurs when an allelic Gene fail to produce a certain enzyme called tryopsine which synthesize a pigment to form melanin.
Albinism is caused by a recessive Gene and itself in a recessive state (aa).
The genotype of a person with normal skin colour is AA.
A person that is a carrier for Albino Gene ,has genotype As.A person that is a an Albino has genotype aa.
For a couple with normal skin colour to have an Albino child,both of them should be Carrie's for Albino gene.
A man that is a carrier for albinism gene married a woman of albinism , high percentage of their children are albinism.
