At a single locus (gene) there is only one dominant allele. This is not always the case, but I believe it to be so with all of these genes. What complicates this story is that there are multiple genes involved, and changes upstream in the pathway (e.g) r or t that impact lycopene synthesis, will also trump B and Del, which convert lycopene to various forms of carotene. Simply if there is no lycopene there is no substrate for conversion to carotene. For the vast majority of tomatoes available commercially, just focus on the R, t and gf loci governing fruit color and Y governing pigmentation of the epidermis. Of course then there are stripes, anthocyanin, etc., which add another layer of complexity.
