Within the Yellowbelly series alleles, which one is considered the strongest?

yellowbelly

Among the five recognized alleles within the Yellowbelly series (*yellowbelly*, *spark*, *specter*, *gravel*, and *asphalt*), the base *yellowbelly* allele is considered the most potent or strongest in terms of visual expression. This strength is evidenced by the extreme phenotypic change observed when two copies are present, resulting in the Ivory Super form, which is characterized by a nearly patternless, creamy-white appearance. In contrast, the other alleles express themselves more mildly. For instance, *gravel* and *asphalt* are classified as the weakest, causing only subtle pattern changes when homozygous, while *spark* and *specter* occupy an intermediate position regarding the degree of coloration lightening they induce.
