Despite what some people would like to have others think.
Piebald and Albinos are both recessive traits. The "markers" are not an indicator of carrying the trait. No one has shown any markers for Albino and the ones for pied can be non existant on true het pieds and can show on proven normals.
Markers are NOT 100%.
Even if markers where 100% positive for a both mentioned morphs, it would not make them non recessive. Train tracks are not the phenotype of a Piebald, period.
