Because the 'ash-red' allele is dominant, scientists think the sticky TYRP1 protein must be preventing other brown/black assembly-line proteins from reaching the proper placeincluding the normal TYRP1 protein thats made in birds that carry one 'ash-red' and one 'blue' allele (this effect is called dominant negative).

Thats because theres enough normal TYRP1 being made from the 'blue' allele for the birds to be able to make black melanin.
