Appearance

Common markers include pale color extending high up the flanks, a lighter tail, and less prominent spotting. Some animals show pale areas near the nose or neck or a light stripe down the back. Expression varies, so appearance alone is an unreliable way to confirm the trait.

Origin & history

Sergey and Raisa Prohorchik trace the White and Yellow line to a female that hatched in 1996.

Genetics

Early breeder reports described dominant-like results. After raising more offspring, Jeff Galewood Jr. questioned that model and suggested that multiple genes might contribute. The inheritance model is unresolved, so the trait has no assigned locus or calculator probability in this guide.

Combination example

Will.iam Exotics documented a Yellow and White Tremper Albino. Tremper Albino is an additional trait in that example, and the animal’s overall coloration reflects the combination.
