Ok sorry for the misinfo but can someone explain the difference between Dom and co-Dom? I'm still fuzzy on that.

co-dom the heterozygous and homozygous form look different, for the lesser, heterozygous is the lesser and BEL is the homozygous
dom means the heterozygous and homozygous look the same, like the pinstripe, het or homo. it looks exactly the same. only difference being the homo. pin will throw all pin offspring, no normals.

Co-Dominant – A visible mutation appears when a single gene at an allele is different than normal. A matched pair of this gene brings about a “super” form that looks different than the single.
Dominant – A visible mutation appears when a single gene at an allele is different than normal. However, there is no known “super” form of the morph.

If by super they mean homozygous, then it is incorrect.
something being recessive, co-dom, or dom has to do with the phenotype (the observable trait)
Recessive = heterozygous - No change in phenotype
Co-dom = both homozygous and heterozygous have a change in phenotype
dom = both homozygous and heterozygous have the same change in phenotype.
i might as go in depth about why
"aa" or normal is still a set of genes. genes dominate or partially dominate over other genes, we classify them by what we can observe, its not just looks, like with blood type they can run tests and observe whats different.
for recessive trait, the heterozygous form "Aa" the "a" or normal gene dominates over the "A" thats why we don't see any difference in the het albinos or any recessive morph, we have to get an "AA" or homozygous to express the albino trait. there is no "a" to dominate over it.
for a co-dom, the heterozygous form "Aa" the"A" gene only partially expresses, it interacts with the "a" gene. while it still needs to be "AA" to fully express. we all know snakes but an example outside of that would be some flowers, white is normal "aa" the heterozygous "Aa" is pink and the homozygous "AA" is red. they the white and red genes both interact with each other, that what goes on in every co-dom we know, its interacting with the normal. lesser-BEL pastel-Super pastel ect. the heterozygous version is always interacting with a normal gene.
Dominate gene expresses the same way no matter if it heterozygous or homozygous. it does not interact with the normal gene it just dominates over it.
