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). The major color locus (a locus is a specific area on a chromosome) controls whether birds are blue, brown, or ash-red. Problems accessing your account? January 21, 2019.
