The allele always shows, makes the recessive
Dominant
The aloe is masked in heterozygous pairing
Recessive
Both alleles need to be __________ for that trait to show
Recessive
Both all show equally like a roan horse or the AB blood type 
Codomanance
Blood typing a BO lies can interact in multiple ways such as classic dominant and recessive traits with the O blood type being recessive to the dominant a or BANB being codominant went together blood type O needs to recessive O Alleles to show.
