A Codominant gene is a gene that only needs 1 copy to be partially expressed, and 2 copies to create a Super form. Whereas a Dominant trait only needs 1 copy to be completely expressed, and a Recessive trait needs 2 copies to be completely expressed.

By definition, the homozygous form of the codominant trait looks different from the heterozygous form which also looks different from the wild type (Normal).

So a Heterozygous individual, let's say a Mojave, only has one copy of the "Mojave" gene. If bred to a Normal, each egg would have a 50% chance of receiving a copy of this gene and becoming a Mojave, and a 50% chance of NOT receiving it yielding a Normal.

A Homozygous individual, a Super Mojave (Blue eyed leucistic), have two copies of the "Mojave" gene. If bred to a Normal, each egg would have a 100% chance of receiving a copy of this gene yielding a clutch of all Mojaves.
