Proof on the Spider gene. OWAL take a look

[reptileexperts]

Not possible. Spider is a dominant gene. A recessive gene can't dominate a dominant gene.

Dominate just means that when two genes are present on the same Loci the dominate one will show the phenotype. . . if a recessive gene was at a different loci it could conceal a dominate gene / be expressed think albino spider . . . So yes a recessive gene CAN dominate a dominant gene at a differnet loci for a different phenotypic (visual) result.
