Sex-Linked mutations must be carried on both X for cocks, and the single X on Hens, for a mutation to be visible. Hens cannot be split to Sex-Linked mutations because if the mutation is on their X chromosome then it is visible. So, what you see is what you get with Sex-Linked mutations on hens. A male is split when only one X chromosome carries the Sex-Linked mutation. The Lutino is a white bird with an orange cheek patch, some yellow pigment, pink feet and red eyes.
Some individuals vary with a light to heavy yellow wash over part or most of the body.
Sometimes baldness occurs behind the crest. This occured during the development of this mutation. Your ideal Lutino has no bald spot. It is very hard to distinguish mature cocks from hens. A common combination is the Lutino Pearl Hen where you find Yellow Pearling over the wings and back.
