Well, if I were to take a clown-like stab at this question, I would say it's the "Don't Mess With Me" allele. It's the kind of allele that doesn't care about recessive alleles trying to steal its spotlight. It's like telling those recessive alleles, "You can try, but I'll always be there, shining bright, stealing the show!" But in all seriousness (or clowniness), the correct answer to your question is the dominant allele.
