Genetics A rare predominantly black cat with odd eyes. The odd-eyed colouring is caused when either the epistatic (recessive) white gene or dominant white (which masks any other colour genes and turns a cat completely white, solid white) or the white spotting gene (which is the gene responsible for bicolour coats) prevents melanin granules from reaching one eye during development, resulting in ...
Waardenburg syndrome is a group of rare genetic conditions characterised by at least some degree of congenital hearing loss and pigmentation deficiencies, which can include bright blue eyes (or one blue eye and one brown eye ), a white forelock or patches of light skin. These basic features constitute type 2 of the condition; in type 1, there ...
Ojos Azules ( Spanish: [ˈoxos aθˈules], 'Blue Eyes') was a breed of shorthaired [1] [2] domestic cat with unusual blue or odd eyes [1] caused by a dominant blue eye (DBE) genetic mutation. The breed came in all coat colors; however, only particolors ( bicolors and tricolors ), colorpoints, and intermediate colors with a characteristic white ...

The gestation period lasts 180 days, or 6 months, after which only one tarsier is born. The newborn tarsier is born with much fur and eyes open. Its body and head length is about 70 mm (2.8 in), and its tail is around 115 mm (4.5 in) long. Like all tarsiers, the Philippine tarsier's eyes are fixed in its skull; they cannot move in their sockets.
Heterochromia iridum. Heterochromia is a variation in coloration most often used to describe color differences of the iris, but can also be applied to color variation of hair [1] or skin. Heterochromia is determined by the production, delivery, and concentration of melanin (a pigment ). It may be inherited, or caused by genetic mosaicism ...
