As was already mentioned, fire is a co-dominant trait. What may need a little clarification is the het (heterozygous) terminology. It was said that there is no "het for fire". Thats true. BUT... a fire IS a het. It carries one of the alleles for the black eyed leucistic. So, it could be called "het for black eyed leucistic". The black eyed leucistic is the homozygous form, it carries both alleles for the fire trait.
