Biological pigment general, contain six ubiquitous carotenoids: neoxanthin, violaxanthin, antheraxanthin, zeaxanthin, lutein and β-carotene. Lutein is a yellow pigment found in fruits and vegetables and is the most abundant carotenoid in plants. Lycopene is the red pigment responsible for the color of tomatoes. Other less common carotenoids in plants include lutein epoxide (in many woody species), lactucaxanthin (found in lettuce), and alpha carotene (found in carrots). In cyanobacteria, many other carotenoids exist such as canthaxanthin, myxoxanthophyll, synechoxanthin, and echinenone. Algal phototrophs such as dinoflagellates use peridinin as a light harvesting pigment. While carotenoids can be found complexed within chlorophyll-binding proteins such as
Cockatiel colour genetics essentially gone. It is only covered up by more grey pigment. There are a tremendous number of colour varieties (combined mutations), including ADMpied Cinnamon, genuine albino, Opaline Cinnamon, Creamino, White-faced Cinnamon, White-faced Opaline. The genuine albino cockatiel is the exact genetic equivalent of any other albino mutation in other parrot species such as the budgerigar, the celestial a.k.a. Pacific parrotlet, the Indian-ringnecked subspecies of rose-ringed parakeet, the splendid a.k.a. scarlet-chested parrot and the white-eye-ringed lovebird species. Throughout all parrot and parakeet species, the genuine albino mutation is always produced by the visual combination of the genuine blue mutation, otherwise known
