In case more than one phenotype is influenced by the same gene, dominance depends on 

a)Gene product 

b)Gene 

c)The phenotype that we choose to examine 

 

Therefore, dominance is not an autonomous feature of a gene or the product that it has information for. It depends as much on the gene product and the production of a particular phenotype from this product as it does on the particular phenotype that we choose to examine, in case more than one phenotype is influenced by the same gene.
