Co-Dominant Gene Explained

Codominant genes - Relating to two alleles of a gene pair in a heterozygote that are both fully expressed. When alleles for both white and red are present in a carnation, for example, the result is a pink carnation since both alleles are codominant.

There is currently only 2 known co-dominant genes in bearded dragons, these genes produce the leatherback and dunner traits, a combination of 2 codominant leatherback parents will produce what is known as a silkback, this is considered to be the dominant form of this gene. we do not know what 2 dunners will produce as noone that i am aware of has paired 2 together.

It has been proven that the american smoothie and italian leather morphs are in fact the same gene as breeders, ourselves included, have paired the two and produced silkbacks. if they were not the same gene, it would have produced leathers and normals, but no silks, or possibly a combination of the 2 different genes producing a completely different morph. (It would still produce leathers as both genes are co-dominant)
