Mendelian trait/disorder: unknown

Disease-related: yes

Cross-species summary: Congenital lack of pigment in all parts of the body. See also Skin colour, albinism, generic

History: Pearson and Usher (1929): "Our original stock consisted of Albino Pekinese and pure-bred black Pomeranians. These albino Pekinese had white coats, the hairs of which contained no pigment granules whatever; the eyes of all of them were characterized by strong red reflex, and marked photophobia. Indeed, on more than one occasion too long exposure to brilliant sunshine has produced something of the nature of a collapse in the dog, who has had to be carried home. The sight of these albinos has varied a good deal, some being so short-sighted that they were apt to run against obstacles, and many, if not all, found difficulty in catching pieces of biscuit thrown to them, which was accomplished promptly by their coloured brethren. This type of albino we shall term the Dondo or White Albino, it is the commonest of all our albinos."

Inheritance: In the results of their extensive matings in their experimental kennel in which albinism was segregating, Pearson and Usher (1929) did not observe phenotypic ratios consistent with single-locus Mendelian inheritance.
