It is a genetic mutation and then, transmissible to the offspring, in an autosomal and recessive way. The phenotype of this specimen could be confused with a red-bottomed lipochrome or an Isabela cake with little brown. But he had bright red eyes that did not alter his color with the unfolding of the canary.
The subfeatherwas pale beige. It was thought that the appearance totally inhibited brown melanins, but this theory was wrong when this mutation was transmitted to brunos.
These appeared with feathers with brown melanin, but with a different organization. The appearance is autosomal, recessive and completely inhibits black melanins.
