**BUT, to be classed as Albino, does there have to be TOTAL lack of pigment?**
n. Pl. Al·bi·nos
1. A person or animal lacking normal pigmentation, with the result being that the skin and hair are abnormally white or milky and the eyes have a pink or blue iris and a deep-red pupil.
>>>> Even in albino humans dark hair retains some colour. The skin of a cremello/perlino is pink, and their eyes are blue. They are meeting the requirements of being classed as albino.
I would tend to agree. Cream *IS* on the C allelle.
Here is another definition of Albinism I found--
"The National Cancer Institute, a division of the U.S. National Institutes of Health, defines albinism as
"A group of genetic conditions marked by little or none of the pigment melanin in the skin, hair, and/or eyes. People with albinism may have vision problems and white or yellow hair; reddish, violet, blue or brown eyes; and pale skin."
Melanin is a dark pigment found in the skin, hair and eyes of humans and other animals. At least in humans, it is also in some internal organs. Dark colored humans and other animals have more melanin in their skin an outer covering (hair, feathers, scales). Melanin comes in two types; red to yellow (example, American Indians and Asians), and dark brown to black (example, Africans). Melanin production is genetic, meaning that it is a feature inherited from the parents of the individual. A reduced or complete lack of melanin production forms individuals we call albinos. There are about ten forms of albinism, some that don't look like what we commonly think of as albinos."
Considering that the people and animals below are classed as Albinos (and from what I can find, all lack normal pigment because of genes on the C series or equivalent), I am wondering why the reluctance of calling double dilute cream horses albinos, or at least incomplete/partial albinos?
