Albino Animals Part-II

Albino Animals Part-II:
Albinism is due to various gene mutations that affect the production of normal pigmentation. True (amelanistic) albinos lack melanin and are white with no markings and with unpigmented pink eyes. Partial (blue-eyed) albinos have some residual pigmentation. There are various degrees of patchy albinism (piebaldism) due to localised mutations in skin cells. Temperature dependent albinos have residual colour on cooler parts of the body i.e. Siamese cats where pigment develops on the head, tail and legs, but not on the warmer parts of the body.
